I have just installed My used D3 into my 2004 Trailblazer LT. Non-Bose has OnStar
Úsed Gmos-01 adapter (came with the unit) I have not got the Axxess ASXC module to work correctly either. And the D3 is really dim Sometimes I am able to see what is on the screen but most of the time it is so dim that it could not be read at the bottom of a really dark well or cave at midnight. (Yes, I am exaggerating a little.) Does this mean my unit is bad or does it have something to do with the illumination wire?
Is there an illumination wire ?
I was sure that I read or saw it listed.
Where and what does
