So has anyone else experienced aftermarket head units and J30s with the car phone installed. This 93 came with a car phone installed and I removed it. I installed the new radio from my 94 J30 and now I dont get any sound from the speakers. When my Dad had his '97 J30 his had a car phone also and he said when he would get a call it would cut out what the radio was playing and use the car speakers for the phone. Is there a way to bypass this or something I have overlooked when installing the aftermarket radio? I get no sound with any of the sources (AM/FM, CD, USB, iPod or AUX)
The cool thing I found the other day was this:

Its a full factory service manual that fits perfectly in the compartment in the trunk near the jack. Never had this in the '94 and the '97 J30 I have owned.
