2007 Tahoe complete electric/nav shutdown



  • 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?

    Any solutions on the radio and blinker issue? Mines at the dealer now and they can't find the problem!!!!!!!

    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.

    Mine has just begun the same after replacing the motor mounts. No radio(sound or display), no audibles(including turn signals) and park assist off! All fuses appear to be fine. I have a 2007 z71 tahoe. I find it very odd that this has happened just after a brake job and motor mount replacement. We have tried disconnecting the battery and reconnecting with no avail so far.
    So is the battery replacement the key to others as well?
    A bad ground terminal somewhere?
    I truly hope that most of you have found a permanent fix by now.
  • Hello All. Ok I'm new here as well and I purchased my 2007 Tahoe LTZ w/nav new and and I've had small issues with the radio and all of the above items. I've over the years have replaced the body control module (which they say controls all) with no fix of the issues and finally our radio just went completely black screen. The issues started with radio sound just popping then would just go off, then the nav would just come on by itself and would show us driving in New York when we were in Texas and would constantly say checking nav disk and eventually just nothing at all. I purchased a new refurbed radio and it's right back to the same issues but now it does sometimes come on at start up and does sometimes will come on after I've been driving for awhile. Don't know if it's still just a bad radio or something else. I've also tried cleaning all of the negative terminals as well. Wish I new if it's just a module, amp or bad wiring thing so I could just fix the stupid thing. BTW I've also tried the new battery thing and nothing. I'm going to try to replace the radio again one more time under warranty. Can anyone please shed some light on this?

    Thnx so much in advance!
