Will Best Buy reimberse me?

I am a supervisor at BestBuy and here's what you can do.  You must have proof from the dealer, a shop manager and the mechanic that worked on the vehicles name at the dealer.  You can turn it into BestBuy and fill out a claim.  They investigate and then decide if there is enough probabl cause that it was BestBuys fault. 

However, unless the installer was a complete idiot, there are harneses that plug into factory wireing that have nothing to do with the car other then the radio.  Another harness runs all the way to the trunk and to the tuner on the drivers rear wheel well.  Best advice like others said.  Pull the radio out, and take it to another dealer, and you should be fine, then when fixed have the radio put back in. 

I can almost promise you BestBuy isn't going to pay you though.  My favorite saying is "Anythings possible, but thats impossible.

heres one for you guys.

 01 olds alero. put in a remote start and alarm. we used a 555l to interface with passlock. now the car doesn't start with the key or with the starter. we took a look at the car and pulled the remote stater completely reconnecting the passlock wires. the car still doesn't start. we talked to a couple dealerships and they told us that there have been many times where the factory passlock device goes bad and this happens, so we sent the customer to one of those dealerships. the dealership then denies ever saying that and says its our fault. I HATE THEM ALL

Well, I got my car back from the dealership. According to the mechanic that fixed the car someone tapped into a wiring harness that fed into the engine and trans, and installed some type of fuse adapter for an "aftermarket accessory"(the radio) and used the wrong ampage fuse, which was causing the circut to short, and the engine lights to go off.

My cost: $111.82

Should i go to best buy with the bill? I have what the mechanic said in writing.
