I've been interested in upgrading from my 7" Uconnect to the 8.4" but after much discussion with infotainment.com (who supplies the preprogrammed OEM units) it has become clear that in order for that modification to work, a dealership must perform a POXI alignment and change sales codes. I have called a slew of dealerships around me in New England and they have all said they are unwilling to perform these tasks. To that end, I wanted to put together this thread so that we can compile a list of dealerships who are willing to give us a hand with completing these mods.
So who knows, posting a dealership you know of who has helped with a mod may inspire someone nearby you to modify and enrich our community! So post away!
