It's been a little while since I posted, but here is a quick update on what I have done to my truck.
I added my RA4 radio (big upgrade from the RA1) and a huge thanks to
@Mpgrimm2 for the harness and helping me deal with shipping issues. This coupled with a new rearview mirror (with mic) and the steering wheel controls installed I now have a greats hands-free set up.
Using Alfa I activated windows global down, compass on the EVIC, Mossy Oak splash screen, and the factory alarm (VTA) without and problems.
Now on to the same problem I have been having since day 1 of the upgrade process. After a few successes, I decided to try and add the premium cluster again and work on the mileage. The first standard attempt got me the same result. This was my first attempt since putting in the Nav unit so I activated turn-by-turn and that works well. That confirmed that the EVIC is receiving information from different parts of the truck, and I attempted to change it again.....still no luck.
Slowly picking away at updating this truck, but I can't figure out the odometer (engine hours and idle hours change no problem).
