Converting an '18 classic 2500 tradesman with the stock 5" screen 4 speed blower fan.

I can't say enough good things about @Mpgrimm2. I bought a 8.4" radio with AA/dual zone bezel locally on Craigslist for $100, the wiring harness and blower components from mpgrimm2. Turns out the radio was a dud, he talked me though some simple diagnostic ideas via email and over the phone, before I ultimately bought an 8.4 AA unit from him. He was amazing to deal with and instructions for installing the wiring harness were clear and easy to follow.

He let me know of the possible blend door issue with the radio and how to solve it w/ an extra dongle and Alpha OBD. Sure enough, my blend door was acting wonky, for anyone interested I found a work around for it w/o having to use AlphaOBD.

My blend door lever goes all the way down when I press max a/c.
When the a/c is off, and I start at 'hottest' temp, lever only goes about 75% of the way down when I press the soft or hard key long enough for the temp slider on the radio to get all the way down. I have to press the soft or hard key another 8-10 times to get the blend door to go all the way down.
I can't say it will work for you, but worked on my truck

Big thanks to @Mpgrimm2 for all of his assistance in my 5" to 8.4 upgrade and 4 speed to 7 speed Single Zone Auto in my '18 2500. All of his wiring harness were perfect for this plug and play upgrade. I'm currently using a dual zone bezel as a single zone and love having the AUTO feature again as well as Android Auto. Collectively, there is a ton of great info from all of the members on here and I greatly appreciate it! Also, thanks for extra help figuring out how to get the Back Up Camera icon on the screen!!!

I'm looking at purchasing a radio off of a 2019 Ram 1500 - 68307855AI.

I'll be installing in onto my 2016 2500. I'm currently using my 8.4 VP3/Non Navi. I bought the navi unlock from navi-uk on ebay yars ago and i'm ready to upgrade. My 2024 F150 got me missing my true navigation and CarPlay.

This radio I know is coming off of a 1500 that has Dual Zone AC, heated Steering wheel and seats.

My truck is fully loaded, with AC/Heated Seats, steering wheel, powered seats, Cargo cam and also Factory Ram Air Ride. I will be purchasing the sharkfin antenna or something equivlant so I can have access to SAT/GPS. So how much of this will actually cross over from my old truck (2016), to the new trucks radio (the 2019)? Will I lose my Air Suspension menu since it's located into my current 8.4 and the 2019 isn't equipped with that option? Also which harnesses will I be needing? The guy wants $400 for the whole thing (bezel included even tho I don't need it), and it's too cheap to pass up on a unit that looks never used and super clean. My issue is he'll only hold it for a few more days and hes a few hours away. Any input with be greatly appreciated.
