Sorry for the delay. High winds, trees down, power out, 'puter dead until a few minutes ago.
The radio should not get hot when the ignition switch is turned off. Any chance it's hot because some heater ducts are behind it? If the radio is still hot after the ignition switch has been off for a few hours, there is a problem in it.
Not sure what to make of the door locks. My only suggestion is there is likely a Body Computer involved. They cause a lot of trouble in other cars. I don't see why Volvos would be any different. Diagnosing that is best left to the dealer.
