I own a 461.model G290TD year 2000.I would to change my radio in this car to a Mercedes APS 30 with navigator problaty to a BE4716 model. For get the navigator to work I need a speed-signal from the car. Usualy in DIN contact terminal A-1.
My question to your expert is, Did I have(or found) this signal from the car somewhere,is it even possible to get a APS 30 navigator to work in my G?
I try to get an answer from my Mercedes dealer in town but they couldnt found an answer.
