To make a long story short, the &*$^*#@! IDIOTS at the local GM stealership managed to burn out/disconnect/destroy the illumination for the display on my radio/CD player, somehow. I didn't find this until the next day, as the sun was shining brightly when I picked up the car, making the display invisible, and of course the LYING piles of steaming horse manure at the stealership just did the LIE and DENY game. They even had some lot guy claim that the radio display wasn't working when I dropped off the car, which is a complete LIE. The stealership are good liars. They have had a LOT of practice, obviously.
I have the 'moon and tunes' package, with the sub woofer in the back of the car.
I also have the XM radio, though I've never used i't use it. The imbeciles at the stealership were supposed to give me a bunch of information about the XM radio, but being lazy morons, they never did. I never got a channel guide, even when I called XM to try to get one. They told me the dealership had them. Idiots. They are everywhere.
I like the stereo, aside from the display being impossible to read if the sun is out. Now it's impossible to read in the dark. I can't change radio stations, use the equalizer, or basically make any changes to the radio or CD output, except for the volume.
My first thought was that the easiest fix would be to buy an identical unit from a salvage yard, and have it installed.
But I seem to remember that there is some sort of security feature, which requires that the radio to be 'matched' somehow to the PCM, (main computer) or the radio won't work.
I think I'm going to have to pay someone to remove the old head unit, and install the 'new' head unit. I'm disabled, and I'm having a harder and harder time working on my car myself. Some dashboards come out easy, and some are a major PITB to get out, to get to the radio mounts.
Obviously, I want to be sure the 'new' radio will work properly. I'm NOT going back to the stealership to have them put the radio in. Aside from the outrageous cost, they are too farking STUPID to even disconnect the battery, when doing electrical work. Who knows how much damage they will do the next time they work on ANYTHING in the dashboard.
Is there any way for me to 'match' the 'new' radio to the main computer? Or would I be better off buying a new aftermarket radio? My car is a 2005, so putting a LOT of money into an aftermarket stereo isn't something I want to do.
Also: is the main power amplifier located within the head unit itself, or is it somewhere else in the car? I don't want to buy and pay to have an amplifier installed, if the power amplifier is wired into the car somewhere.
One thing is for sure: I'm NEVER going to take my car to a GM dealership, again.
Many thanks!
