The new Qstarz BT-818X bluetooth GPS receiver comes with the second generation MediaTek GPS Chipset (MTK II). The MTK II has better performance, boasting 66 channels compared to the previous 51 channels. The MTK II has an impressive 42hrs battery life and an extraordinary fix speed.

The Qstarz BT-818x comes with Assisted GPS (A-GPS)

A-GPS is a system where outside sources, such as an assistance server and refernce network, help a GPS receiver boost performance beyond that of the same receiver in a stand-alone mode by downloading the almanac data from an assistance server.
