USB Navigation Update for MAZDA 6 & CX-5

Two weeks after we released USB navigation for SONY XAV-601BT, XAV-701BT, we got another USB navigation system on our compatibility list: MAZDA 6
& CX-5 Now these models are all available for external GPS/Glonass navigation, 3G and wifi network, and TMC receiver provided by Wonde Proud's car navigation.
