A couple years ago I did a retrofit kit on my 2015 Expedition to upgrade from Sync 1 on a 4inch screen up to Sync 3 on an 8inch screen (non-nav unit). I’ve followed countless guides and sought help on how to relieve this issue, including setting the IGS bit, but I’ve never been able to fully solve it. I’ve read around this forum and it seems like I may be able to get some help from here, including getting a proper AsBuilt config for my setup. Many thanks in advance.
My bad, I’ve heard it referred to as the Illumination Gateway Strategy (IGS) bit. It’s the change at 7D0-06-01 that is frequently mentioned. I believe that’s what you’re referring to as well?
Yup that’s the one. Try maybe putting a zero in the second bit. A 15 Expedition is a CGEA 1.2 vehicle, but it should work on CGEA 1.3. C1MCA will not work for sure though.
