Well I keep digging myself deeper into the hole.
The Keg wouldn't play either the original or the new (80GB) DMS, so I repaired the original, and put the Kenwood firmware onto it, which didn't do anything.
I took the Keg out of the car, took it apart and made sure othing was loose. Everything looked fine. Put it back in the car and now instead of being called HDD EXT, it was AUX EXT, and nothing looked like it was being registered through the headunit. The green and red lights stayed solid for a few seconds, then the green blinked slow for a few seconds, then blinked rapidly for 3-4 minutes before turning off and rebooting only to do this sequence all over again. Nothing showed on the headunit.
Now my Sirius box will not work while the Keg is plugged in. I have to keep it unplugged if I want to listen to Sirius. It will recognize the Sirius Tuner, and even download the information, but I do not have any sound while it is plugged in.
Tomorrow's tasks are going to involve disconnecting the Sirius box altogether, and plugging the Keg directly to my HU, to see if the Keg is recognized, and see if the firmware loads up properly or not. Something is definately done for good, don't know if it is the Keg or the Sirius box, but I'm hoping the latter.
If anyone has any ideas, I'm listening.
