Gentex Onstar Mirror Wiring

[\"Doc\"-sqrd]

Hi Klaus,

Regrettably, I was unsuccessful in getting the Gentex mirror to function despite your wiring diagrams, calls to Gentex and Onstar! There is an apparent mismatch in versions of Onstar...so mirror selection may be very critical. I was using a 2002 GMC trailblazer mirror...so don't try this one! I did get the Pioneer Nav system up and running with the Onstar buttons moved to between the A/C center vents. It looks unobtrusive and real nice in that location. BTW I missed the Gilmer outing! One of my partners has an orange H2 and we crossed paths with paragon on his way home crossing US80 (we were returning from the Longview gunshow...(fun but not as much as Gilmer would have been!)

As for the install, the mic is tucked in next to the overhead console (no sunroof version), the Pioneer head is in the Onstar 1/2 DIN slot and the touchscreen panel is in overhead #2 (folded up when not in use), my sunglass holder is mover to #1 next to the OEM H2 mirror.

Thanks for asking!
