Actually this is old news.
I hope everything else is all right. I am sure if it was more catistrophic even with the radio up you might have known.
Same thing happened to me. Get with Jerry, he will make it good on the pulley, You need the new style. You will have to get a new belt and there are much cheaper resorses than the dealer price of 105.00.
Summit racing has the best price. About 50 bucks
Didn't all your warning lights go on?
PS at least your happened near the garage, mine blew apart in the middle of no where, 104 Miles from home ad to the cost a near $500.00 tow!!!!!!
