He is sending it out to determine cost to repair. I don't expect to know anything until next Wednesday.

We also found the Mediabridge was not working It was acting up before the install so I was not surprised. No way of knowing which happened first though since initially I lost the 20 seconds of sound and then the next day it was back before it went away and never came back, I think the Mediabridge failed first and then one of the several attempts to get the DSP amp working fried it. Having two issues that were contributing to the problem made it extremely unlikely I was ever going to fix the problem. That's based on the tech expertise of 20 years, how long it took him and the testing equipment he used. He huddled with his other techs a couple of times to recap what he had done and get their opinion of what he planned to do next.

FYI, the black wires in the white connector are video colors. Once we got them connected properly the Nav unit colors were normal and could see that functions were working properly.
