The new Qstarz BT-816X 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 32hrs battery life and an extraordinary fix speed.
The Qstarz BT-816x 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.

66-Channel Performance for fast acquisition and reacquisition
Super high sensitivity -165dBm adopting latest MTK II chipset
Lower power consumption up to 32hrs navigation time
Less than 15-Sec. AGPS fix support: download almanac data to realize faster TTFF and positioning under warm start
G-Mouse + Bluetooth in one: wired and wireless GPS receiver
5Hz update rate for higher accuracy of the demand of eXtreme Sport
Fast Position Fix ,Cold start 35s, Warm start 33s,Hot start 1s
Personal/Portable Navigation (PDA, Smartphone, PC, etc.)
QZSS, DGPS(WAAS+EGNOS+MSAS) support
Auto On-Off function for smart power control
