I know there have been a million posts about the avic d3 bypass. I just want to make sure with my truck that there isnt anything special that needs to be done I have a 2003 GMC Denali. The Navigation unit has been installed already with the blue tooth adaptor, Ipod cable, and steering wheel button controls. Besides grounding the parking brake wire after removing it and putting into positon above, will the installer need to do anything with the speed sensor? Anything else i should tell the installer? Thanks for all help everyone out there
Maybe you should have read one of those million posts first.
