#### Bluetooth data exchange protocol optimized **GEN7 GEN7(V2) E96(V2) S96(V2)** The data exchange protocol has been optimized for changing settings via StarLine 2 mobile app over Bluetooth or through an external GSM-GPS module. #### Xin Long YT-F-C-12-W parking heater control support added **GEN7 GEN7(V2) E96(V2) S96(V2)** Control and monitoring of the Xin Long YT-F-C-12-W parking heater control via digital bus has been added. Supported when connected into the break of signal wire between timer and heater control unit. Use two wires: grey and white or white-blue and white-green to connect. In StarLine Master program set one wire as "Xin Long YT-F-C-12-W parking heater control via data bus (timer)", and the second - "Xin Long YT-F-C-12-W parking heater control via data bus (control module)". On "Engine Start" tab, in "Parking heater (preheater)" section, enable "Control parking heater (preheater)". For "Start type of preheater" parameter set "Xin Long YT-F-C-12-W via data bus" option.
