Disconnecting Trafficmaster SmartNav
Today I have the opportunity to trace the wires where this aerial goes. There is a black box on the front passenger footwell with a blinking LED light. It marked Port Alert M/Europe Smart-Nav UK. I managed to trace it to TrafficMaster in the internet.
This box really consuming battery resources that my reason to disconnect it. Anybody could guide me how to do this without impairing the working of the car?
