I took the car to a mechanic. He thinks, I hve to replace the
Display monitor. 2095.00 65 52 8 380 593 - Part and the Housing with cassette deck.

It sounds strange to me because I don't know why a bad display would cause the radio to cut out every 90 seconds.

Scott Did you ever find out what was wrong with your car and what they did to fix it? I would assume this is a common problem.

thanks
