Antenna under armrest is the bluetooth antenna

The TCU needs the adapter from the BITII wiring because the pinout is different.
Do not plug in the BITII connector to the TCU directly!

The coax cables are bluetooth antenna, GSM antenna, and GPS antenna.

GSM phone = violet
GPS = blue
Bluetooth = cream

The sharkfin on the roof is GSM phone antenna only (not GPS)

The bluetooth antenna under the armrest connects directly to the TCU
