I just bought an OEM nav unit off of ebay, which was unlocked (didn't show theft-lock when connected). My tahoe didn't come with factory navigation, but has Bose and RES.
The radio powers up and all functions seem to be working perfectly accept the volume control ****/digital pot. The volume is at or what seems to be full-on 100% all the time and will not turn down. Strangely enough, the power on/off function of the volume ****/digital **** works fine. Has anyone had issues with this before? I am taking the tahoe in tomorrow to get my new 2-way remote programmed. Does anyone think that this issue might be fixed by resetting the BIN? or Programming with Tech2/TIS may fix this? If not, does DENSO sell replacement digital volume pots???

Nav radio issue - please help!
Hey thanks for the reply! I took it to my chevy dealer today. They reprogrammed the radio and programmed a new 2-way advanced remote that I installed. The radio volume problem was fixed, or so I thought.
The tahoe was parked/turned off initially after programming. It worked just fine after I started it up and drove home from the dealer. I returned to the tahoe to drive across town approximately 1 hour later and the radio had no power and the park assist was disabled.
Can anyone help here???? Did the dealer/tech possibly forget to save anything to the ECM? Has anyone had this problem?!? The tech person also told me that he disabled the backup camera feature because my tahoe doesn't currently have the camera (not that this would effect the power to the radio)
NAV is GM part number 15882766 by the way...

Ok new update... I unplugged the power to the radio and plugged it back in.
The radio power returned and the park assist is now re-enabled. I turned the car on and off a few times, and the power dissappeared again, but the park assist didn't shut down this time. The tech at the dealer said this is pretty strange. The radio is warm to the touch, but the tech stated that this is normal. Although I have BOSE, after programming I noticed that the BOSE logo when the radio powers up has dissappeared. Could this be because the tech misprogrammed the radio?????

I installed the navigation disc today as well. The GPS located the initial position of the tahoe. The GPS did not track the movement of the car and the buttons and screen became significantly delayed while the disc was inserted...
ANYONE HAVE ANY IDEAS???

Maybe you need to reprogram it again and look for additional options in TIS
If it worked properly after programming - it must be ok. Donno what happened after switching off, try to check wires and harness.
I think it's better to show up this problem in dealer's office, where it was programmed. I still have no camera signal, cause I can't find a Rostra interface harness, but my tech serviceman enabled the signal from cam, so I can connect it anytime by myself. Still I have no problem with the sound. Hope you'll solve this riddle. Don't forget to inform us how.

If not, it's selling separately from head unit.

The company selling the harnesses on ebay have phone support at (1-800-881-8207). You can also purchase the harness over the phone. They include directions for installation. I will be installing this on Wednesday Sept. 1 and will keep the forum updated. I'm taking the tahoe back to the dealer on Thursday Sept. 2 to have the radio reprogrammed. If it doesn't work, I think I'm just gonna give up and send it all back.

As an update, the radio hasn't lost power any today, so it was possibly a loose connection.

By the way, this Navi is properly tracking without VSS here (i mean in Russia). It was tested on several cars with Delphi-Denso navi systems, so everything is ok. However, GM Navi is not so comfortable and direct as Garmin or HP, so I'm not using it as usual, just trying to make all the OEM options working properly.
Now I'm downloading 2008-2009 Navi program (compatible with LR, RRS and Volvo Navi) for Europe and Russia, so I'll notice you about results with pictures.
