Hello Everyone...

I have a 2001 TT Roadster with the Bose Concert + 6 disc sound system. Originally both the CD player, and the radio were working (as they should be). Recently, my battery drained pretty low and it was a rough start, when the car finally came up the 6 disc changer wasn't being recognized by the head unit. I purchased a VAG-COM cable to check if any codes were coming up. Using VCDS-Lite I accessed the radio options, the radio went into DIAG mode and then stopped responding. I started the car and now the head unit and the media display by the tach/speedometer are both blank. If you have any ideas on how I can gain functionality back I would be greatly appreciative.
