I have a question about my CDR220 that I am using in my Cabrio for more than a decade. This is a low mileage car and I noticed a couple of months ago that the unit starts operating normally and when I drive a short time (~ 1 minute) the unit shuts off completely and cannot be restarted while driving by using the "on button". When I stop and turn the ignition off, the unit starts again as it is supposed to start and shuts off again after a short time. I ws able to replicate this behavior a couple of times.

Have you seen this before? Any guidance on how to trouble shoot?

Thanks

Does that unit have a removable faceplate?
If so, it may just be a matter of snapping it off and back on for improved contact.

First, pull the radio out a little and check the plug and grounding strap.
Some units have internal protection against speaker short circuits. If your speakers are the original 20-year-old ones I would check their impedance.
Also to be reasonable the radios in our cars if original are 20 years old and may have dried out or failed internal components as well.

Thanks for responses. Yes, it has the face plate but I took it on and off which did not impact the behavior. I have upgrade the system 10 years ago and have "new" speakers. At the end, I have to pull the unit as suggested and check the connections. I can than make measurements at the plug to see if the proper voltage is at the plug. This should allow to identify if the supply / cables are the issue or if there is something with the unit. Thanks again for help and I will keep you posted with my findings. In addition, I want to upgrade the unit to bluetooth with the new Becker kit:

You could try sending the unit to Becker Auto Sound in NJ. Experts in these units and reasonably priced.
