Chevy Silverado and GMC Sierra Audio/Radio

We currently own a 2005 2500HD Chevy Duramax 4x4, which for the first 30k miles has done very well powertrain wise but its been the little stuff. There has been a rattle in the steering column which as I understand is caused by the new steering system that GM has used in the GMT800 as opposed to the old CK platforms. But now the radio is shutting off. Sometimes when your riding down the road the radio is on and all is well, it seems as the vehichle warms up the radio is more apt to fail, Any input on what this may be?

    Most stereos/radios have a heat sink and a cooling fan. If your fan has stopped working, it could lead to a buildup of heat in the unit forcing it to shut down before permanent damage is done.

    The stereo in my 99 silverado has finally given up the ghost. My question is, is there a certian way to get it out of the dash, ie, schematics, so I dont break the plastic all up.

    Hey evil,did you ever find out how that stereo comes out?
    I just bought a 2006 1500 silverado wt that came with am/fm only and want to put a stereo with a cd player in it eventually. Just wanted to know how much of a hassle it is.

  • My radio keeps on resetting itself at random intervals. I'm not sure if it is when I turn it on or off, but I start it and my clock is back to 1:00 and my presets are gone. I've tried driving with all the lights on to see if that would trigger it when I started it the next time, but it's still random, about 1-5 days, sometimes twice a day. It won't kill me but I'd like to fix it.

    Remove the trim piece around the radio by pulling on it the whole piece will come off. If you have an automatic you have to shift to first gear and tilt the steering column all the way down. then, you will have to remove the radio by pressing the 2 clips down on each side of the radio the radio will slide out. Then just disconnect the wiring.
  • ijust attempted to get a new stereo installed in my '03 sierra and found out that i supposedly need an additional 150.00 part... needess to say i flipped out!
    what is a gmrco1? how important is it? what does it do?
    can i just move on and not bother with this thing?
    thanks for your help.

    What most likey it is a module (just for aftermarket radios)
    so you will have door chimes, key buzzer,etc. after non-GM
    radio installation.
    All GM trucks 03? and after generate all their warning chimes THRU the factory Delco radio and sound off thru the
    left speaker.

    $150 bucks is pricy for this module if in fact that is what it is.
    Have you asked a good stereo installation shop about this?

    BTW: YES you can install a aftermaket stereo and not use this module........But no warning chimes!

    I have a 2000 silverado and in the second year of our truck my cd player quit working. I have had no luck getting it to ever work so i just left it, I listen mostly to just the radio anyway. But now about 3-4 months ago we noticed the dash lights on the am/fm/cd unit, some lights quit. The preset buttons #2 and #5 and the SEEK button do not light up. Everything else lights up like they should as anyone every had this sort of problems????
  • wgreen,
    putting a stereo in the 06 shouldnot be a real big issue. However keep in mind that there are 2 ways of doing this. One is buy a harness piece that runs around 50 bucks at cruchfield or you can wire it without but you will not have the bells for if you leave your lights on or keys in the ignition. I just put a pioneer (er had it done) and there is plenty of space and the dash front comes out very easy.. almost 2 easy for theives etc. But i put a new deck new speakers and a small 8 inch sub behind seat and it sounds very very good for under 500 bucks. looks nice in dash also... doenst look like aftermarket.

    Which Pioner did you buy.
    I have a 95 Sierra with a cassette reciever, I would like to install a cd/cassette reciever - was this available on a pre-2003 Sierra/Silverado. I am low budget and want to know what to look for in the Junk yard. Some of the local yards ask a thousand questions before they look up a part or allow you in the yard. :( :confuse:
  • I have a 1999 Sierra 3/4 ton with the AM/FM Compact Disk, Cassette, Clock Package code - UP0. The CD player needs to be replaced. It is a remote cd player mounted down just above the console. It tries to read a cd, kicks it back out, and gets the code ERR. Have tried cleaning and resetting via unhooking the battery cable with no luck. I went to the dealer and they want $35 just to take it out to tell me how much it would be to replace. So I would like to do that myself. I removed the two screws inside the cd storage compartment below the cd player. The top part of the trim is still attached to the side molding that covers the area above the hump, but I can't see where or how. At that point I think I can remove the cd player and probably order a cd player myself.

    Can someone tell me how to take this out without tearing up the plastic molding?

    Is there a book I could order that would cover this type of repair for all the interior?
  • Thanks. I have done a lot of searches and none brought that up. I looked and GM also has them so I think I'll order through the dealer and save shipping (I hope).
  • I have a 2007 Sierra Classic and I hate the fact that there is no Accessory position for the key. I want the radio to stay on when I shut the truck off, even if I open the door.

    Is it a simple matter of rewiring the power to the radio direct to a constant 12v?

    Any information, especially radio wiring info would be appreciated. Thanks.

    I have to install new 5.25" speakers in my doors. I was just wondering what the wattage output is so I'll know what minimum wattage speakers to purchase.

    Thanks for you help.

    Some radios can drive 25W/channel to 2 Ohm speaker load directly. Some only capable of driving 4 Ohm only. In that case, the maximum power output drops significantly (10W per speaker for example)

    But all of that with a disclaimer: full volume setting and may be 10% distortion. Some cheap radio could not drive 2 Ohm speakers but most can do 4 Ohm. Normally if you set your volume 1/2 way, you're lucky to get 1W output/speaker.

    In addition, radio has Distortion Limiter: it will back volume down or even shut down if it is overheated and/or could not drive Low Impedance (2 Ohm) speaker.

    So radio is also a limiting factor. But if you want safe option, the new speakers should the same Impedance (4 Ohm or 2 Ohm) as the ones you replace. Typical OEM speakers are the cheapest things they could find in China or other low cost countries. Any decent high performance After-market speakers will improve the sound greatly even with the same load spec. The difference is the Audio frequency response: cheap OEM speakers have little BASS or TREBLE and more distortion.

    If your audio system has the external amplifier like Bose, infinity, Pioneer... then the limiting factor is not the radio head anymore. It is now the Amp that needs to match your speaker loads

    I can't get my 6-CD player to read my music data discs. I burn them with Windows Explorer as file folders for albmuns and within each folder are several .wma files. When I put the disc in the player, it responds by saying it can't find anything on the disc. Any solutions?
  • obyoneobyone Posts: 8,065
    You need to convert the wma files to wav for your car stereo to recognize them.
