Subject: Update- I have power on pin 8 &15 of 15pin conn. There's nothing on I-bus/pin#5 Author: bmw635 : 15687 posts Posted on: 2007-12-03 22:23:33

of 18pin conn (no ohm/ volts with key on pos#2)- what I am supposed to look for?

Given how it's behaving, I assume the DSP amp is OK since it was working after the initial TV test( TV has no audio), then it was shown in the display but no sound after dead batt, then disappear completely after hard reset/ batt disconn.

Short of removing everything reconnect the old radio to restore DSP, do you think recoding will make it work? Do you think swapping DSP amp to test would work? Thanks again.
