Does anyone know of a site that will compare the specs of different bluetooth GPS models? Like channels, power requirements and est battery life, size of unit, standards within unit like WAAS, things of this kind? I have been looking for info on some of the units including the Garmin GPS 10, but just can't seem to find any of the specs for some of the units. Thanks.
http://www.gpsinformation.net is a terrific site but I don't think it does much with the huge number of $120 or less bluetooth GPS units out on the market today. http://www.pocketgpsworld.com/item-menu.php?idSubCat=5 seems to have a lot of reviews though I never saw them before doing a search this morning.
I'd suggest looking for a unit that has a SiRF III chipset. If you're looking for navigation in the car I don't think WAAS is a huge need though most come with it. Depending on where you live and your view of the WAAS sats it might be a moot point anyway.
For me I was looking for a unit that had good battery life, wasn't huge and came with a way to easily recharge. I went with the Globalsat BT-359 which is small (but not keychain size), long battery life and mini USB rechargeable.
I have Navibe GB737 and works great...
In the GPS & Mapping Forum at BBF (can't post a link yet <10 posts), there is a sticky thread titled, "GUIDE: Bluetooth GPS Pucks". It was very helpful for me in choosing a GPS.
While it doesn't have a comparison chart, there are explanations of the major chipsets and popular models of each. Also includes links to the manufacturer websites.
