2007 Tahoe complete electric/nav shutdown



  • Just wanted to make sure I am understanding correctly, amygray27,
    You've visited a dealership for them to look into the stereo concern discussed earlier in the thread and they weren't able to resolve it?

  • After doing more research online it looks like the solution is to replace the amplifier that is in the center console. It's at least a $500 part, so I have not changed it yet. 2 things that I've noticed are it seems to happen a lot less frequently at cooler temperatures and if I turn the key to the "on" position for a second before starting, it also makes the problem occur less.
  • I'm having the exact same problem just today. The screen on my nav/audio system won't even come on it's completely black and dead. On too of that it's saying the parking assistance is turned off. It's really pissin me off... Are you for sure that the amp being replaced would fix it? Thanks for the help.
  • I'm not positive, it's what I've been able to find out researching the web.
  • Did anyone figure out how to solve the problem? Mine is doing the exact same thing
  • Starting to experience this problem on my Tahoe now. Does anybody have a solution to this problem?
  • I'm having the same issue now that I think several others are experiencing. Radio, chimes etc. are cutting out and it seems to be the amp like others. I guess my biggest question is can I just replace it with an aftermarket or do I have to get another $500 (with labor) oem? Anyone got experience with this? I've had suburbans for 15 years now but, I'm about through after this one. Thanks.

    My 2007 Tahoe just did the same electrical radio, nav., DVD, blinker and chime as the others I was told I need a new radio? I did see recalls for electrical but it was not on this. I had problems with a 1998 Chev. truck, and it burned in my front yard at night. So I and hoping this has a solution cause he is saying a new radio is $1,200.00.

  • The radio in my 2009 suburban has been "glitching" out every few minutes for the past 3 months. When this started happening, my Bluetooth also stopped working. This morning the radio completely died. My audio screen still works -I can see the stations - but there is no audio at all. The blinker sound also isn't working. I ran it into the dealer and he said the radio probably would need to be replaced. I didn't have time this morning for him to run any diagnostic tests on it. Has anyone run into this and had it fixed?

    I ended up changing my battery and going up one size. That was about a year ago and it seems to have solved the problem. With the old battery, it happened several times per day.
