I just found this forum about 3 days ago, and I just want to say THANK YOU!!
At the beginning of the month, my Kenwood HU started "losing my Music Keg". I took it back to the installer, and he thought it might be the cable. After he did a little checking, we thought it might be the Kenwood Sirius Tuner... I did all the reformatting, reloading firmware and resetting I read about. I eventually called Kenwood, and they had me do the same things I had already done. No luck. I kept thinking this can't be hardware that needs to be replaced, but I was at a deadend! I was at the last resort of sending the Music Keg in for "repair".
However, I kept seeing PhatHack in my Google searches. but was still coming up empty. One day I saw the forum...long story short: I read about someone saying the cable inside the Music Keg being loose, and never being one to be afraid to take something apart, I opened the Music Keg and the ribbon cable was indeed loose!! I plugged it back in, loaded the DMS back in the Music Keg, and eventually it came back on. I have removed it, started the car, removed it again about 5 times and so far so good!!
Sorry the post is so long, but once again Thank You!!!
