Summary
TELEMATICS SERVICE INFORMATION HINT: This bulletin applies to vehicles equipped with a 4G network compatible TCU. TCUs compatible with 3G network only are no longer supported. SERVICE INFORMATION The APPLIED VEHICLES that come equipped with a factory installed SOS switch, located near the overhead map lamp, also come equipped with a wireless communication device called a Telematics Communication Unit (TCU).
