Sorry for the delay............
If the disconnection of the 2010 Mirror has caused the Message Center Error:
Quickest way & better way, would be to reinstall the original Mirror & Reprogram or fix the Message Center Error.Then, using the "same" Factory Harness "Relocate" the 2010 Mirror elsewhere, under dash, out of site.Install the old Gentex as that should have it's own Harness & would need to be wired in anyhow.This way the Factory Equipment is not bothered, will not mess with Warranty & Compass should work in Message Center without Error Message
Then I must have misunderstood your question.
Sorry for the confusion..........
There is no way for the Gentex wiring to be incorporated into the 2010 Ford to make the Message Center read correctly or to keep from "reseting", as that is a DATA Type circuit & without the 2010 Compass being connected, the same will happen.The way I suggested, "will" keep all wiring intact & not cause a problem with Warranty.The only other "possibility" is to Reprogram the BCM to tell the Message Center that there is No Compass
I have been installing for Muth & Gentex for over 15 years & would not supply wrong info.The older Gentex Mirror, has it's own Harness & cannot be incorporated into the 2010 DATA of the Message Center.If you want trouble free, have them relocate the 2010 Mirror & install Gentex by itself, not using 2010 Ford Factory wires, which it appears that is what they did.The extra 2 wires were probably the Reverse wires. Most do not hook those up. When vehicle is put into Reverse, it is supposed to Dim Mirror
