I went into store came out started my car and radio has no power. The light won't come on at all not even the "safe" so I can enter my code. I have checked the fuse in the fuse panel area it is OK. I have removed the radio & the fuse in back of radio is OK. I have unhooked the battery and still is dead. My radio is Bose for 2002 Audi TT. Are any other fuses I don't know about or any reset buttons?
You push the FM 2 and RDS buttons simultaneously and hold them down until 1000 lights up. Use station buttons 1 - 4 to enter your code. Then simultaneously press down the FM 2 and RDS buttons until the "SAFE" appears.
I some how solved my problem. I removed all 50 plus fuses and replaced them (because one dealer said it might reset the computer). Then when I was going to remove my radio one last time before taking it in to the shop my radio powered back on. I might have been a loose connection at the back of the radio.
