That was my goal, but the more I talked to folks it's not possible on the 2017 hardware in the Pacifica even when attempting to cross flash a firmware from a 2017 Charger, Challenger, or 300 due to a VIN check in the firmware. I also learned that the 2018 hardware of the Pacifica they changed from Harman to Panasonic and different USB connections.
Hopefully in time someone will crack this nut, but so far Infotainment and NavRepair.com said not possible
