Recently we had our 2006 Chevy Trailblazer LT radio with NAV/BOSE unit replace with a new one. After we got our truck back we noticed that the chime was so loud that you can barely stand it. After talking to the dealer they said that they cant do anything about this. Does anyone have the same problem and is there a FIX??? Please help me I cant even use the NAV unit with voice, it is entirely too loud.

 

Welcome to the TB forum. Not sure how the 06s work (I had an 02) but my 07 Tahoe has a menu pick that allow chime volume to be set.

 

The 06 has a setting on the radio for Normal and Loud. I have it on Normal now and it is still loud and Load is ear peircing loud. This all happened when my GM dealer switched out my old Bose NAV radio for the same one cause we had way too many CD's stuck in there, thanks to the kids.... And the dealer says that this is a problem that they have had before and supposedly GM is trying to fix it. It is just taking way too long for them to get it fixed, I am almost at the point of having them replace this radio and try my luck with a new one.

 

this happened when i had my 05..dealer couldn't resolve my problem so i replace my radio and bought a chime..problem was resolved..might be the radio that has something funky going on

 

I recently changed out my factory stereo without Bose & installed the GM chime clip to keep my chime. What you have to do is:

1. Turn the vehicle off but leave the key in the ignition.
2. Open your driver's side door.
3. Push the the dimmer switch in for it to pop out & you can turn it clockwise or counter clockwise & that should adjust the volume of the chime.

Hopefully that works for you.

 

I can't rememebr for sure what button it is, ....with the radio off, push and hold preset 6 untill there is a beep and the radio will display high, push and agin for med, and again for low.
hope this helps
