Hello everyone. I have three problems that I should likely attempt to repair at the same time.

1: Missing wire to nav screen for rear entertainment system, know what to do hear.

2: Passenger door tweeter not working and seems to not be getting any feed from amp, problem is mine is an 07 (logic 7) model built in 06 which seems to have conflicting speaker wiring diagrams one says its tied with midrange speakers and other says it runs direct from the amp, the tweeter has a resistor wired in so I’m thinking its tied to the midrange.

3: still no low range, garage thats been working on it figures its the shift motor. When you push the button to select low range absolutely nothing happens, no lights or messages etc just nothing. Has anyone come across this? I’m wondering because the auto garage is seeing about having the unit rebuilt but on this vehicle a new one can be bought for like $200CAD, rebuilt for $150CAD so at those prices I don’t understand why they wouldn’t just replace it unless they aren’t sure. They have pulled a new set of codes which I don’t have, worth note is that with the diagnostic equipment they can engage it no problem. Anyone know how to diagnose the switch?

4: with interior removed to deal with video cable, not working tweeter etc I think I will run 18/6 cable from the back fuse box area to say front of centre console just incase I want to add switching for auxiliary lighting etc. Has anyone with the full audio system found the need to run any wiring from the back to the front for anything? may as well future proof all I can.

Thanks for reading my long post.
