When I first turn on my car the stereo and A/C works fine but as soon as the car reaches temperature the radio, GPS screen turns off and the A/C turns on and I have no control over it. I would appreciate any help you can give. Also, I'm located in the Baltimore area, any advice on where to go to get this fixed is very much appreciated? Thank you

This is not a radio problem; this sounds like a classic IPDM problem which controls the power and operation of the systems mentioned. To be sure we should do a CAN scan, you can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

here is a video to show you how:

Here is how to change the IPDM out in case you need it. It is easy to replace because it-self learns.
