[..]  Plenio VXA-4300 Works OK -- I give it three stars, because it has worked for over a year now. Would not buy one now, because Plenio does not make updated maps available, so maps are over a year old. As a result, it can not find any new streets or addresses. In addition, the rechargable battery lasted about six months. I now have to plug it in whenever I want to use it now. I will not buy another Plenio product, because the product support (maps and operating system updates) is poor. I suppose that's why the cost of the product is low.

[..] Terrible out of the box, but good for geek (me) who likes to tinker -- Where do I begin? The POI is lacking and outdated, upgrade map is not available, short battery life (less than an hour), screen is not the brightest. However, knowing all that, I purchase one anyway because the price I found was too good to pass up last year (well under $100) since I know I can add application to make it a more powerful device. This is because it runs on WinCE OS (not to be confused with WiMobile OS on mobile phones/PDA) and the software are right on the 1GB SD card. Just buy another a 2GB (under $10), copied the 1GB SD card to it and have fun customizing it the way you like. You can start by search for the phrase "plenio VXA-4300 wince forum" on your favorite Search Engine for more information. Just a warning, this is really for those who like to tinker with technical things, aka IT guy/geek. [..] -- customer review
