Loose ground wire or bad ground.
There was interference with the radio signal.
XM radio does not have static interference. It's a digital signal, so you'll either get a crystal-clear sound or none at all.
to avoid radio signal interference.
Electrical interference in a car radio is the same as electrical interference on any radio. Radio interference is literally the sound of the air. When a radio signal is broadcast, the frequency that was previously only occupied by air is overpowered and drowned out, thus you hear the broadcast frequency clearly. When the broadcast frequency is weak (i.e. you are too far away or something is blocking the signal), the frequency cannot completely overpower the air and thus you hear some of both.

you probably have a short in your wireing
Concrete interferes with wireless communication by weakening the signal of the radio frequency. Concrete's ability to weaken or completely stop radio frequencies from travelling through it are what causes the interference.
Sensitive devices like microphones working at verylow level can and will pick extraneous signal from many sources solution is to shield the cable so the signal will be hard to influence a double shield scheme is desirable whereby the interference will be routed to ground
Your radio signal works by using its signal to go to a tower and back to your radio (Via antenna).
A satellite signal will be a radio signal. And a radio signal in space travels at the speed of light.
Check for a loose fuse, check your wiring, check the connections, sounds like something is loose. Also make note as to when it turn off, are pressing the brake? using the turn signal? I had a firebird that every time I press the brake the signal lights would turn on and the radio would turned off, that turned out to be I used the wrong bulb in my brake lights
Electrical interference is messing with my radio reception.
