do not go to best buy. i got what i thought was a good deal through them to have one installed on my wifes car a couple years ago. set up my appointment, dropped the car off mid afternoon and recieved a call to pick the car up a couple hours later. go to pick it up, guy tells me right off of the bat that they couldnt get the trunk release button to work, so they just gave up on that. it wasnt a huge issue, so i just let it go and proceeded to head home. walk out to get in the car and realize none of my dash lights work. tried every switch, but nothing. i walked back in and told the guy about it and he tells me he is finishing up with an install, then he will look at it.
ended up going out to dinner and walking around walmart for another hour until they finally call me. headed back over just to have the guy tell me that all he did was search online forums to see why the lights werent working, hands me this 10 page print out about how the dash lights are notorious for going on my car (2000 bonneville), and tells me that if i want to go buy all new bulbs, maybe we could work something out to where they would install them.
i ended up telling the guy no, it was in your posession when they went out, it needs fixed or my lawer will be involved. got a call a half hour later saying it was fixed, they dont dont know what happend but appearantly they just ended up beating on my dash until all of the lights came back on.
