It's good that you got it "fixed". It's the same thing as most other complaints.. check the wiring, and then worry about something more substantial!!

My concern was that even if you have lost your receipt, doesn't the company that did your installagion keep records on what they do to what car??? I'd expect that even if I didn't have my receipt that any reputable place would have their own records.

Having said that... I know that if I didn't have the receipt for my audio so far I'd be stuffed if anything (else...) went wrong. It's been hard enough getting something to happen on the problem that I've had, so I'd hate to think of what woud happen if something else was the problem.

From a personal point of view, this is why for things like this that I consider important, I'd go to a specialist place and not some big chain store for it. I don't know where you wen,t but I hope that they would at least remember the car, of not have the record of the job!
