Uupgrade

[Grammyshelly]

I just purchased a 2500 with ra1 radio. I want to upgrade to ra3, backup camera, and trailer brakes. Would the 4 speed fan bexel still work if I swap out to the new bezel that accomodayes the 8.4?

I don't think the old bezel will work. the upgrade has more buttons instead of dials for what vent the air is going from. I might be wrong but I don't think it will work without a conversion plug for the hvac unit.
