I have installed a Motorola BT Carkit (HF850). One of the wires can be attached to the stereo to send the call through the car speakers. I need to find out which wire on the back of the stock unit I attach to.
I talked to one installer and he said to use an SRS capable test light and ,with the radio on, probe each wire until I hit a wire where the sound goes off, then hit it again and it goes on. Supposed to have something to do with switching from radio to CD.
Anyways I did this but no results.
Any thoughts on which wire is the right one?
