Got car back from dealer... just love driving in 2 hrs of traffic jams with no music (unless you consider honking horns music, if thats the case then you might consider some of the hand gestures tv!) because the radio (concert II) was in safe mode. After pulling over to read the ambiguous manual, I came to the forum when I got home to find that there is a lot of mystery on this issue. Here is what I found/did.

1) Just because you pull the fuse or remove the radio, does not necessarily mean that you radio will go to safe mode. The radio looks to see if other modules in the car are the same as the last time it was disconnected( removed, fuse pulled...). Therefore I assume that your radio could be working fine... you have your cluster replaced, but the battery was never disconnected, therefore your radio will NOT go to safe mode until it has reason to believe that a power down condition exists...

Okay, enough theory, when I got in the car the combo RDS and SCAN buttons would not bring up the code entry screen. Also the manual does not state how long to hold the buttons, but I found that if the code entry window does not appear in 10sec. it is not going to. After driving home, I still could not get the code screen. Pulled the fuses, still no luck. Re-read the manual on the 'cycle' which is quite ambiguous, (pg 25/26 audio manual.). So I parked the car turned the ignition off, turned the radio on (safe mode) and let the car sit. An hour should be sufficient, but I left it all night. In the morning, the code screen appeared while holding the RDS and SCAN buttons for less than 10 sec. For those who dont know, you code should be in your audio manual front page. My head unit was replaced in the past, but the code has not changed.

If anyone who has facts on this issue I welcome them to add to this post. I am not the expert on this issue, but if you search the forums you will find a lot of VOODOO on this subject. This is what has worked for me. A very frustration issue.
