8.4" to 12.1" screen replacement

Also when u rewire the plug if you touch the red and ground (duh) which they are close and right next to each other you will blow fuse f53 under ur feet.
 
I have been trying to follow the thread but its 10 pages long. So if I have the 8.4 w/nav in order to change to the 12, I need the screen and make sure the module comes with it?
Nevermind u don’t need the Lvds if you have Navi sorry
 
thanks, im looking at some on Ebay, would you be able to tell if the module is there in the pictures? The reason I ask is the seller has not replied yet.
This is the correct one for the 12.1 couple online places said 2 weeks will be released

Well I called the dealership with the part number 68317978AI and they are not allowed to sell them yet only to trucks that have it
 
Do all the 12" screens come with the ability to use surround view? Do the rear, front, and side cameras come into a wiring harness that goes to one plug or are there 4 places in the back of the screen that accepts 4 cameras? I am wondering if once the 12" monitor is installed with the radio module, maybe you could also install the side mirrors and front grill with cameras and wire them in, or even use aftermarket cameras.

surround camera is available on the 8.4 also. No the screen has ONE input. The surround camera has four cameras that feed into an image module. It handles all the inputs and sends out the signal to the screen.
 
Good news I found a junk yard that is sending me the 12.1 module so I’ll update ASAP
 
I have a 8.4 with Nav and purchased a 12 with module that came with it . When I hooked it up. The screen was blank and wipers went crazy. It would not work . I then installed my Original 8.4 back and the heat , radio wouldn’t work and I got a bunch of dash lights. I took it to dealer and they had to re program the truck and told me the AC module blow out. All of you that have the 8.4 with nav, Do not plug and play—- warning
Do I need another module ? Were do I get it and what part number is it?

Just a recap on the info we have here to make the conversion from 8.1 NON Nav to 12.1 Nav:
Rewire cable with blue tape to match 19RamLimited Picture
get cable to override 911 message: https://www.infotainment.com/products/911-vehicle-phone-override-cable
get LVDS Cable: https://www.factoryradioparts.com/p...e-differential-signal-jumper-cable-05064684ad
get Radio Module: 68317978AI
get 4c Uconnect Navi 12.1 screen.

Is this accurate to make a FULL conversion? or am I missing something?

Sounds to me like you have it figured out. Please let me know when you get everything working because I want to do the same thing.
 
Anybody here has a RADIO MODULE FOR THE 12.1 or a lead?

68317978AI

Really wanting to make things work, got the screen from Bill and lvds cables already just need the 12.1 module.

What did you start with and what parts did you install?

Any programming required?

I have the 8.4 with nav and all I had to do was get the radio and the module no programming was required all I had to do was get a unlock code cause it was locked there’s a company online you can get that with the module s/n radio codes.com
