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.Not sure what you're trying to do here. Are you trying to enable Carplay or Android Auto on it? If not, what is the difference between 3rd and 4th Gen ?
I am also interested to see if we can enable Carplay on this.
Hopefully in time someone will crack this nut, but so far Infotainment and NavRepair.com said not possible
