Just installed the AVIC-D3 but now I'm getting static shocks....

When I set my feet on the ground and exit the vehicle I go to shut the door or touch any metal and get a static shock! The D3 itself is working properly as well as the the Sirius Pioneer PNR2 unit. Onstar works perfect as well.

Is it not grounded correctly? How would I find the short if there is one.


Here is how I hooked everything up:

I used a GMOS-01 Harness. I used the bypass mod and grounded the parking brake wire coming from the AVIC and the MUTE wire which I moved to the above PIN (Tested the AVIC with no errors and plays DVD's while driving). I grounded them to the harness Ground wire which was connected to the factory harness.

For the PNR2 I connected the power to the GMOS-01 harness Yellow wire. And the ground to the GMOS-01 harness as well.

This is a 2007 Trailblazer. I could really use some help on this one. Thanks!

I NEVER use the grounds in those harnesses, run the grounds to a bolt behind the dash.

What would be the symptoms of a bad ground?

it can take so many forms that it's hard to tell. Oftentimes it's unexplainably poor performance or alternator type whine in the system.
