Other Comments: The QSTARZ BT-Q890 GPS receiver and bluetooth transceiver is a small rectangular device measuring about 1.5"x2.5"x0.25" or 38x62x7mm and comes with a keyring attached to the device by a small strap, a USB charging cable, and cigarette lighter charging cable. This is the smallest GPS device that I know about and is advertised as a 66 channel GPS receiver. On the Nokia N800, the QSTARZ device has to be paired with the number 0000.
