Radio wouldn't turn off
Last week I was driving home with the radio on, and when I received a phone call I hit the button on the steering wheel to answer. Usually the radio stops playing, and the blue tooth/phone starts. This time, I had radio and phone on at the same time. Hard to hold a conversation with the radio on, and everything seemed locked. No volume control, couldn't turn it off, couldn't disconnect the phone. I was able to disconnect the phone when I turned my blackberry off, but still couldn't turn off or control the radio. When I got home, I turned off the car and the radio was still on with the key off and in my hand. Finally was able o turn it off after pulling out the radio fuses in the rear of the car. Pulling out the radio fuses in the glove box did nothing. I put the fusess back in, and everything working normal now. Any ideas what this is? Car is a 2005 X5 with Nav, and blue tooth. Phone is a blackberry bold with touch screen. Thanks!
