My SL55 has been sitting for 6 weeks due to a vacation for me in the hospital. The car has been started and run several times over that time period but not driven. I drove the car for the first time this morning to my office and the radio did not play. I also tried to use the CD magazine and the display came back "Device not found". Could the problem be that the car has not been driven and what should I be doing to get it back to normal?

Thanks

It still could be a low voltage induced problem - did you have a battery tender set up for the time you didn't drive the car?
In case not, you might want to try to just remove the +plus+ battery terminal from the trunk battery for 5 minutes, albeit, you will loose all settings. Or have the dealer run diagnostics, either solution might be a pain.....

After driving the car for about 10 minutes the radio started working again but the CD mag would not work. The car sat for about 5 hours and the CD is now working. All is well.

It'll probably happen again. Happened with my C55 and my SL55. I kept a wrench in the glove box and disconnected the ground on the battery every time the stereo would give out. Would work fine for afew weeks after, then I do it again.
