NCS Navi R120 is one of the thinnest bluetooth GPS receivers out there at only 0.93 cm’s. (but do check out G66 at 0.63 cm’s). R120 just got the FCC approval to enter the U.S. market with its slim profile and 15 hours battery life. It uses the MTK low ability consumption GPS

Chipset which is capable of searching satellites in 51 channels for fast acquisition and reacquisition and has -159dBm sensitivity.

This bluetooth GPS receiver comes with a USB style car charger and currently the only place you pick one up seems to be eBay for about $75.
