Re: Autocom wiring
Esco, I believe that you're correct: the 2.5 mm is the speaker plug, and the 3.5 mm handles the mic.
Rather than butcher up the existing wiring harness, I think my best bet would be to build my own cable using a 2.5 mm female, and a 3.5 mm female, with the wires terminating in a 4 "pin" male adapted to the needs of my phone. I should be able to check the pin assignment by dissecting one of the useless hands free sets I got with the phone.
At least that way I can still use the Kenwood, should I ever decide I need or want it.
The only other concern is the stereo aspect. Although it's not needed for this application, I'll just have to test the radio to see if I hear it though both speakers. If that's the case, then I don't need to worry about sending a left and right signal. Even if I had to send left and right, a jumper should cover it.
Thanks for the help.
