Before posting a statement in accordance with international practice, click: the program of the posts talk about, talk about brands. In the OEM market is currently doing
PND (portable navigation device) program is nothing less than to so few R & D companies. The brand is more like river carp. In addition to new subjects, Malata, Garmin, MIO, the other brand products which are derived from several basic solution providers (R & D company). Although the posted
called \To achieve the above objectives, I will use the evaluation data and pictures to prove.
milk cat is GPS businessman, also GPS players, based on the above two factors, milk cat program maturity and level of attention to quality than other users to intentions.
articles in this quote is not the gunmen - at least so far no one give money. Far as this year (2009) spring and summer in the PND market for portable navigation device to make a comment only. The old rules, like the students to call a good, pretend you do not like the students did not see; or need to refute me, please use the objective data and facts, rather than \some meaningless words a strong sense of personal subjectivity.
need to discuss and exchange students are also please do not add qq, and two posts on the cat out of milk,
belstaff online, leading to the opening of the two qq k-plus members are also critical for direct-mail contact:
zezorainbin@gmail.com . This post is not opposed to reproduced, reprinted, please indicate the author, after all, Page Zi and evaluation is not an easy thing.
The following text begins. The A4
GPS time finally arrived, though a little late for that little.
called A4, is a Sirf Atlas IV short, also called the 4th generation of Centrality, which is built on the ARM11 architecture on a chip, the key is applied in the PND (portable navigation device) on.
A4 has any good?
a fast speed. A3 products, the basic measurement are in the 325Mhz frequency, while the A4's frequency can reach 533Mhz; the benefits of faster speeds is obvious: both the fluency of operation or navigation software running and path computation, are far better than A3 products.
II, Star Search soon. Improvement of the internal operation mode and the increase in the number of channels, to involve many of the technical parameters are not discussed in detail here. I only said the results: in good signal conditions, the basic positioning can in 20 seconds or so; in performance under weak signal is also very good - of course, this also, and MEI (cell interference) suppression is related to various companies and programs factories there are still gaps between products, but overall, it is stronger than many of the product A3.
Third, video playback support more perfect. As chip performance improvement, smoother video playback, the software also will support post to rmvb format. Although this is just a software upgrade, but for users, this is undoubtedly a great news. Because most of them are online video download rm format. Machines in the A3, if want to see a movie, often need special software to convert and compress, which is a more complicated work, and A4 of the multiple video format support, will make users more willing to accept it. In the time it is not used for navigation, if coupled with CMMB function, this thing looks more like a portable entertainment devices - could listen to music, watching movies, watching TV, reading e-books and so on.
more importantly, A4 is not because of its powerful and expensive. In fact, only from the BOM costs, it will not cost much higher than the A3. This means, A4's debut, will be squeezed A3, and A3 are not going to dance. In the upstream, this conversion is now at the beginning; in the terminal market, the fourth quarter of this year, the product should be a rare A3.
This is a trend no doubt - A4 era has arrived.
times in the A4 is still talking about a few programs that still the mainstream companies: Yuan Feng, palm information, Ai Peike. (Saida this did not mention the United States because they do not launch A4 products, they have been taking the platform Samsung + GPS module, I will post another review Samsung evaluation program of secondary articles and A4 compare programs. )
far peak times in the A3 market share of products accounted for the majority, 82C motherboard has become a model from the time work until now. Of course, good does not mean that products sold must be the best, can only prove far from the peak of the very successful marketing. The companies on the A3 program product evaluation, a post in my other \far from the peak in the ARM11 architecture
pioneered the 84T on the motherboard, using a SIRF-PRIMA control chip, clocked at the nominal 600Mhz, full-featured configuration, equipped with CMMB, av-in, fm and other functions,
belstaff blouson, and match of 2 Genuine (beta) Maps - good products, but always able to come up sales. This is not surprising, the cost is too high, oem not acceptable on the market a few. Far from its peak of only their own brand of acco struggling to advance.
here to insert a period, SIRF-PRIMA and SIRF-Atlas IV difference: simple to understand,
belstaff sale, they are similar to intel's Centrino and Celeron difference. PRIMA nominal frequency of 600Mhz (currently not the right software can test out to see the value in the TCPMP is 270Mhz, Oh), the technical parameters with more powerful performance; and A4 are nominal is 533Mhz. In fact, in PND can present the application procedures, the gap between them is minimal - the contents of this evaluation in the back, I will use the data to speak.
peak soon realized 84T far the price cut is not suitable for OEM market. It introduced the 84A, which can be understood as a simplified version of 84T, using the A4 control chip, the same hardware configuration of the motherboard subsidiary 84T cheaper than the 200 yuan or so. In fact, A4 and PRIMA not such a big price difference, which is far from the peak the company's marketing strategy only. However, 84A product appeared more strange BUG, such as CMMB, receive and play less smooth, rmvb format video playback is not smooth; the stability of 84a with far less original 82C, led to a number of factories in After the small batch production have adopted the attitude.
Yuanfeng available in the market again in 82A, which is a board-and 82C exactly the same product, just replaced the master chip from A3 A4. 82A in the market, but also very dispirited.
first introduced in the preceding two distant peaks A4 (PRIMA) platform motherboards suffered a Waterloo, so manufacturers and distributors are all generated far from A4 peak psychological fear.
Furthermore, the current A4 map (D version) is not much support for: domestic in the A3 on the map can have more than a decade, and in the A4 with only four or five on the can; foreign common IGO and r66 Map A4 is also not well supported.
another point, 82A CMMB no built-in functions. When a PND PND CMMB a selling point when the lack of this feature can also cause some bad effects.
a direct result of this phenomenon: we are on the far peaks of the A3 platform, 82C motherboard, and for much of the new peak 84T, 84A, 82A nobody wanted to touch the. The occasion of much frustration peaks, only with a marketing tool used: Buy 10 82C, with the N-chip must 82A ... ...
there is a far external factors affecting the peak of the market: the peak is far off the motherboard. A false peak of 82C motherboard far really cheaper than 4 dollars or so. At least from the user's point of view, they almost can not identify genuine and ######## - who sell Taiwan navigator to give you allow you into pieces out of the demolition of the genuineness of the motherboard Chou Chou? Li Gui emergence of the far peak is definitely not good news.
seeing far more staggering peak of vigorous walking.
Ai Peike A4 in the wave of the slain and turned back.
to look back, Ai Peike 2440 Samsung 703 products for the platform is a classic. When Ai Peike by it, in the PND market has occupied a half. Pm to more than two years later, there is still a vendor at the specified 703 in the list.
However, the times to A3, Ai Peike the 728 and 828 of the products with poor performance and instability of Star Search is known, (unstable down and Ai Peike little to the R & D team, reportedly because of their cooperation in the factory replacement parts caused by theft). A number of factors have led the sales and reputation Ai Peike waterfalls.
By April this year, I got a Aipei Ke developed on the A4 platform, G930 prototype. Rom the time there are many bug, not too serious evaluation, only a general impression: Run fast, Star Search soon, CMMB smooth, does not support rmvb format video (after the new software versions are supported).
to the end, finally got Ai Peike production in the A4 platform product, G930 and G963. Both products are finally made to my fresh and new.
G930 of the plate followed the original 728 on the A3 platform motherboard, can be applied before the shell; from the hardware configuration and price positioning, should be put away as opponents 82A peak - and it Excellent point than 82A: An optional built-in CMMB. Currently on the market seems not intend to 82A peak far motherboards equipped with built-in CMMB function.
Ai Peike the 963 and far from the peak of the 84A (84T) interface is fully general, are also taking the thin line, but also through TF card to expand capacity. In other words, this board can be loaded Aipeikede in any one of 84 board for the far peaks custom housing. Hardware platform from the point of view, 963 and 84A which is almost exactly the same two motherboards are equipped with the A4 in the CPU, all built-in CMMB, or even the same standard of memory, is 4GB. But in fact result in the use of, or different. 963 wins, one chip than 84A, but with far-chip equipped with a prima tied for peak 84T Kankan. This is a detailed comparative evaluation in the future, we can see. Ai Peike 963 motherboard launched the intention is clear, is far from the peak of 84A cut a piece out of a share in, as to how much one can cut, we will wait and see strike.
rumored upcoming Ai Peike a 940 motherboard also has yet to get accurate technical information, is not clear is based on the prima or atlas4 platform, only that it is ultra-thin shape to go the route, with is the TF card expansion capacity, as is not only on the basis of the 963 changed a little bit plate, other configurations are the same, it would not know.
In addition, according to reliable sources said the Ai Peike A4 platform will launch a new motherboard to support high-definition 800x480 resolution screen machine, this is really a great news. With PND frequency of the upgrading, CMMB functionality added, and support more video formats, this thing will soon become a portable multimedia entertainment terminals, rather than a navigation device. As a portable gadgets like high-definition screen, users will no doubt bring a more perfect visual experience.
Ai Peike also the UI (Human Machine Interface) open out to end users. PND in the industry now, UI seems to be a not a big secret of the - if you want to customize its own interface, even if it is simple to change what icons and background images, the program's sales staff will gently ask you: You need to customize the number of tablets (units)? By convention, no three-five thousand board orders, customize your own personalized menu of this idea is impossible to achieve. When it comes back again some more cattle, and even the boot screen all into a big problem.
UI aesthetics for each person is different,
belstaff uk, and perhaps you will enjoy calm the screen, you will find the silver black UI will be more equipped to your satisfaction; and Wang Mazi students to like the cute little picture of Q because he is a very young bubble MM, dreamy cartoon interface will be more discussion of her love; Lee students just full of cauliflower, red second hand Swift, she considered that the interface is more red wine to meet the maturity of her femininity and with her car ... ... solutions company,
belstaff brad jacket, we are of course not possible to customize so many different UI.
Thus, Ai Peike decision: Do you love toss, right? Nazan will give you some of the UI released, go toss your own. That the tools provided by Ai Peike software, you can put your favorite pictures, sounds and other material from your computer and shift it into the navigation station which - in the portable navigation device in the open to the user interface, DIY, fully The allows users to express individuality, which is very interesting.
in and a few large processing plants and brands when it comes to Aipei Ke, we have a common view: A4 era, Ai Peike was back then (703 products) feel.
, of course, talking about Centrality, and one can not fail to mention the solutions company: palm hearing. Compared with the far peaks and Ai Peike, fortune and material information in financial resources is a relatively small company. However, information in the palm of micro palm 3 generations, they developed the product is very good. Also in the ARM9 platform, built on the A3 board, palm inquiry PV4X series of motherboards than the distant peaks of 82C and Ai Peike 728 strong, the performance of both the search and software implementation of star performance, it is no doubt The one step ahead - and even Samsung S3C24XX + SIRF3 module compared to PND platforms, performance is quite close. But, financial and marketing reasons, the palm inquiry PV4X series did not take too much time in the share of A3. However, once exposed PV4X series of senior players and some have a higher demand on product quality manufacturers, will firm select it.
course, the palm-Link's products are not foolproof. The PV52 is another headache for many companies. PV52 was 5-inch screen for the development of a product, and PV4X board increase compared with the built-in CMMB functionality plate is also slightly different. The birth of this board is full of twists: First, the display is a problem of supply chain, followed by the stability and speed of the motherboard is also unsatisfactory, and finally, CMMB has a problem ... ... PV52, so that information not be able to palm A3 draw a perfect finish.
Then came the era of the A4, fortune seemed to be somewhat slow pace of inquiry. Yuan Feng, and Ai Peike products have been waged, I just saw the magazine industry information A4 palm inquiry advertising - a high profile, to promote inquiry A4 palm product support 800x480 HD screen. But to wait for more than two months later, the palm is still hearing the HD A4 still holds partly concealed, has so far failed to meet even a prototype. Through other channels'd get a few days before the hearing of a charge of the A4 platform is already known as a production machine, but unfortunately is a common screen (480x272) of the 68 board.
a rough assessment of a moment, a bit disappointed: with the A3, like the UI, the same plate, the performance is also quite satisfactory, there is nothing to feel themselves. Accidentally, thought it was the product of their A3 - just in the system inadvertently saw the word Atlas IV, to be convinced that palm information A4-platform development work. Perhaps my expectations too high strike.
In addition, the UI is also a charge of hearing the millennium change. The first edition of the UI interface - refer to the words of a friend at that time: the aesthetic standards of their art in the twentieth century, still remain the standard of the eighties; customers reflect the more, the charge of Information launched a second edition UI, This version IPHONE copied some elements of its form without obtaining the no choice but to God, to draw a tiger not a like a dog. Fortunately, the quality of the product itself is superior, the customer only had to accept its UI, Oh.
but,
belstaff jacket, surprisingly, the palm 68 of inquiry for evaluating products in a major stand out - one of our test is a weak-signal test, weak-signal test, including several links:
1 High downstairs test (so-called \\(Horizontal angle 90 °)
because the satellite has been in a different light and weather factors, to guarantee the fairness of the test, we selected the following table of six different types of machines the same time and the comparison test. The charge of the performance information is very surprised, search Positioning fast beyond our imagination. It appears that Palm is still followed the information age PV4X series of excellent signal A3.
below gives a list of products to do more than talk about an aspect ratio right. evaluation value to low level
were ABCD.
A representative of the performance is very good, excellent; B represents a good; C means that the function only in a passing line position, barely can be used; D means that the function of poor performance, or use can not be used in difficult to state.

Note:
one master chip and the measured frequency. Evaluation of six machines, only 84T prima use the main chip, the official nominal is 600Mhz, but I do not use TCPMP test out shows frequency only 270Mhz, which is not correct, so, in which no marked out.
Second, the expansion card. Support the high-speed large-capacity memory card, 1-16GB cards were used to test before, there was no incompatibility
III, FM transmitter results in connection with a 12V car charger charge state test, FM FM 99.00Mhz, firing distance of about one meter away.
1, far from A4 peak full range of products (82A/84A/84T) evaluation of the project have failed, FM noise emitted large, small voice of the Lord. Even close to receiving the radio again, and no significant improvement. This feature basically had no practical value; 84T slightly better results a little bit, but also poor performance.
2, Ai Peike the performance of the 930 and 963 product line. The signal emitted rounded clear, basically no noise. But in the case of the charger does not have emission signal is very bad.
3, No. 68 in charge of hearing the perfect product launch signals. Charger must also be access to as a transmitting antenna. Sound quality and Ai Peike close, FM signal level Biaipeike slightly smaller.
Fourth, navigation software compatibility. Respectively downloaded Kay Rucker, Inter-City Link, Lingtu Skywalker, Route66, Malata high Tak run the test, can enter the program, to locate, perform basic operations, we consider the program can run in the machine . Program can run more than 5 adopted, as the adoption of the test. Navigation software because there are not many other wince6.0 system implementation, so the highest score of the test only B
down after a test found that 68 of the palm inquiry screenshots software products can not run, so in this Evaluation of a level to low scores.
five, CMMB, Futian District, Shenzhen, the basic test to the normal viewing of the indoors. Good signal area. Each machine are not out of an internal antenna.
1, far from the peak does not support the built-in cmmb function 82A;
2, 84A in the ratings process a little picture cards, ratings cctv5 sports program, this drawback is particularly prominent; in the same condition, the other 4 Assessment The machine did not shed a signal is occurring, and 84A are often not receive the signal, automatically resume after a few seconds;
3, 84T occasional off signal, the picture smoother than 84A, but not as good as the other 3 machines;
4, Ai Peike the 930 and 963 in a perfect performance in the evaluation, the evaluation in the win.
5, News 68 pictures palm smooth, but occasional full-screen mosaic Huaping, estimated signal is lost cause. In addition, palm picture information than the other receiver screen several delayed by about 1-2 seconds.

1, far from the peak of the 82A does not support rmvb video format play, at least in our hands this prototype is the case;
2, 84A to play the video clips very card, lost Frame serious;
3, 84T play more smoothly, after all, prima nominal 600mhz 的 CPU is not covered; but in the process of playing all cards that look every few seconds, suspected to be fast enough to send the card led.
4, Ai Peike of 930 to win in this evaluation, smooth playback screen.
5, 963 playback screen with cards, do not know the difference caused by the rom version.
6, palm inquiry board is a 68 point card.
seven stars weak signal search results. The tests measure the basic parameters A4 machines are not too bad performance, significantly stronger than A3 products, many times. So the minimum scores are B, while the inquiry is particularly prominent palm, it gives the ultra-high score of A +.
1,82 A 82C compared to the same gate signal much better, although all of the A4 navigator is the weakest performance in a; in a very weak signal state of poor performance.
2,84 A par performance and 82A between the two machines so it got the lowest score.
3,84 T's performance is far from the peak than the other two products is better than A4, 930 basic and Ai Peike flat, but the 84T, after all, is prima with the CPU, the cost of lying here, if the performance was generally so no justice to the.
4, Ai Peike 930 outstanding, which can easily deal with a variety of harsh signal environments.
5,963 because the slim design, the relative size and position of the antenna are affected, in the test less than 930.
6, Palm News 68 won out in the test. In the \3 other sets is just barely a few minutes with the successful positioning. Palm News 68 tests in this project no doubt far ahead of the competition.
Summary:
These are currently (summer 2009) the three programs is summarized the company's products. General market trends can be seen:
far peak 82A is intended to be used to directly replace the 82C product, it can be seen from the configuration is to go low-end market. But the market phone-filled, new meteoric rise, 82A whether the market share of inheritance from the 82C, it's not good, said;
84A is taking the side line, built CMMB, increase the screen, ultra-thin form factor is a selling point. Look forward to the next one fell swoop would have swept most of the terminal market share, but unfortunately the product is not satisfactory. And Ai Peike of 963 to exactly the same as the plate is in the arena at this time, directed at the 84A, intended to plain - at least the scores from the evaluation point of view, 963 in performance is beyond 84A's. As for the 963 can do the marketing plan to what extent, it is not the scope of this article.
84T terms from the price, of course, high-end line, not the current configuration and 84T each equal to the product appears. But the highbrow, and the view from the evaluation, 84T far from corresponding to the price so it is perfect, but only 930 Kankan and Ai Peike inquiry and palm tied for No. 68. From the cost point of view, 84T is not a good choice.
Ai Peike 930 was supposed to replace the A3 728 times, at least in R & D is exactly the same plate. Opponents should be much the corresponding peak 82A. But down the evaluation, 930 of the configuration and performance well beyond the 82A, and even better than in the far side of the peak positioning 84A. Positioning a low-end products to mid-range ahead of the competition, at least that it is good value for money.
and palm-Link's products, a number of dark horse in the era A3, A4-time, remains.
