I had issues using the newer VCIM in my 07 LTZ. It worked perfectly but for some reason at random times during driving, my nav/radio/all audio signals(including turn signals) would shut off... literally no power. I would have to pull over, pull the radio and amp fuse under the hood and re-insert. I removed the new VCIM and have never had a problem since. Like I said... the functionality worked and was great but wasn't worth constantly having to have this side-effect.
I honestly never figured out why it caused this and not sure if it's tied to all 07 models or just something buggy with mine.
I am having the same problem as WingsAA. I have tried two different VCIMs in my 08 Tahoe Hybrid - the first was out of a 2011 Tahoe and the one I have in there now is out of a 2010 Suburban. Both of them work fine, but after driving for a few hours my radio will freeze and when I hold my steering wheel button to engage onstar, it just beeps twice, and will not work.
I haven’t pulled the fuses, but I have to pull over and shut the car off, open the driver’s door to shut off all the electronic signals, wait a few minutes, then start everything back up. Once I do that it works fine for a few more hours BUT this is a HUGE hassle.
I have been thinking about adding a switch to the fuse and running it inside the cabin under the dash. That way when everything freezes, I can just flip that switch (cutting the power), wait a sec or two, then flip it back on….all without having the stop and turn the car off then back on.
Has anyone else had these issues? I’m sure it can’t just be me and Wings. If so, what did you do to fix/correct it? And do you think that adding the switch to the fuse is a workable solution?
Thanks for your help! I look forward to hearing what you guys think.
