Pontiac Grand Prix Audio, XM and Onstar



  • og512og512 Posts: 2
    I just bought a 05 GTP and I have the 6 speaker RDS system that plays MP3 cd's. I was wanting to get the XM satelite service. Do I just go to the dealer and ask them to add it on or do I need a different factory head unit?
  • Does anyone know how to remove the factory radio from a 2006 grand prix?
  • I have a 2006 Grand Prix with a radio that occasionally skips for a second or two. It's intermittent (no pattern that I have noticed). Other than that it plays very well. Any ideas as to whether there a setting that can adjusted or if thais may be wiring or antena problem would be appreciated.
  • My GTP's radio controls started acting funny. Now, when I hit volume just keeps going up...and the same for volume down. ALSO -- randomly, the volume will go up or down on it's own. Does anyone know how to fix this? What part is needed or anything? It's getting to be very irritating!!! THANKS!!!

    When an afternarket radio is installed, there is a bypass unit/adapter that you can buy to keep the factory beeps, as the beeps originally go through the radio. You can also get an adapter to bypass and relocate the stock radio to somewhere else (like the trunk) to retain these features. I have the first of the two.

    The problem is that I think the radio keeps the date information in it. When you set the date on the DIC (Driver Information Center) with an aftermarket stereo, it displays only for a few seconds, then goes away and displays dashed lines where the date would normally be displayed. You can do this as many times as you want, but still, the date does not display permanently like before, when the stock stereo is installed.

    Is there a way to get around this without having to get an adapter that bypasses and relocates the stock radio? Any input would be greatly appreciated. Thanks!

    we have OnStar,but it is not activated,and it is on the analog system that is no longer available,but the phone will not turn off,and it continues to dail out GM told me my headers were gone,because the radio will not play,can someone tell me what the problem is?I would like to have my music back,my 2004 is dead without it.

    I found out that if you disconnect the battery cables and leave them off at least five mins. then reconnect,the phone on onstar stops dailing,and everything is fine,also.....,if you let the phone continue to dail out it WILL run down the battery,but once charged everything will work as it did before.The dealership wanted $95 for a diagnostics check,and told me it was my headers on my stereo,and that this would run me $150 to $200 to get it fixed.
    LIARS I would have spent major money,for them to disconnect the battery cables and reconnect them.Oh and in a 2004,pontiac gran prix,the fuse boxes are as follows; one under the hood ,on the passengers side panel,and two is on the passengers side,inside the car as you open the door look on the side of the dash.
  • I have a 97 GT. I have the Delco AM/FM/Cassette/Equalizer deck in the dash with the 12 CD changer in the trunk and Steering Wheel controls and HUD. I have two problems:

    It appears that the bulb is burnt out in the display. How do I get to it to replace it?

    The CD Player is only reading 4 of 12 CD's and has troubles starting even on those 4. Has anyone had the same problems? Any advice? It is an expensive item to replace and I would like to repair it to save money if I can.

    Does anyone know what an E20 message is on the CD player? I insert a CD, it makes some noise, then the I get an E20 error, and the CD ejects.

    Anyone know what this error is?

    The CD player may need service -- to be cleaned. I believe I had gotten that code once on one of my GTP's and that was it. chats1
  • I have taken out my factory CD player due to it skipping all the time and replaced it with a pioneer CD player but the controls on my steering wheel will not turn the volume up or seek or fm/tuner change.on the new CD player. Does anyone know what I done wrong or if I can fix it. I have enjoyed the controls on the steering wheel and dont want to lose that option.
