If you are looking for a cheap Bluetooth GPS get this one. QSTARZ BT-Q816 32 Channel Bluetooth GPS Receiver ( Same as Q818 but smaller batt) I look all over reading reviews for all types of chipsets. And this one is the bomb. It is better then my friends Garmin SiRFIII chip. At 54.95$ its killer. Battery life is great super fast GPS fixesand lock ons. It's better then my Magellen Explorist 200. I purchase mine from below and it came faster then they said. I did 4-6$ ground shipping and it came faster thent there 5-6 claim. BTW: I use it will my Dell D620 laptop, T-Mobile WING PDA, and N800. No problems what so ever. Only one issue I have with Maemo Mapper when I turn off the bluetooth link it crashes Maemo mapper. No biggy just restart and all is fine. http://www.buygpsnow.com/qstarz-bt-q...mount-835.aspx One of the great things about this GPS is the auto off works killer. Trust me dont look anymore just get this one. I do sick research and this one is every thing that I read about.
