Chrysler T&C radio - is there a reset?

What is your question?

Is there a reset button (or hole) for the radio on a Chrysler T&C radio? We had some electronic work done on the accelerator and after leaving the shop the radio works but changes station every 2-5 seconds. Very strange and I'm just guessing that the shop electrical work caused some spurious signal that messed up the radio and hopefully there's a reset somewhere that will make it right again. I did disconnect the battery for 3 minutes to no avail. Shucks. Any ideas? Has anyone had a similar experience?

What makes this problem better or worse?

Never works now.
