Has anyone found a source for the radio module?

And they say it works with both the 8.4 and 12" screens. I don't know if I'm brave enough to order from them.

I would like to switch from the 8.4 to the 12.1 what do I need to do to make it work.

I have the same question. Just bought a 12 inch off eBay and trying to install. Looks like the harnesses are different. I'll keep you posted.

Ok.. let me try to clear up what I said.
The main plug is the same.

What is different - the 8.4 Non Nav is a self contained unit.

the 12.1 and 8.4 nav have a brain mounted remotely and the screen is fed through a combination of a standard plug and an LVDS cable. The plug has power and can bus so that will not be present in the truck with 8.4 Non Nav( I do not think) and would have to be wired in.

Since you have the 8.4 Non Nav you would need the 12.1 brain the LVDS cable the main plug is the same although not certain that it will reach where the remote brain is mounted in the other since the plug goes to the center stack on that one and where the brain is on the others

The other thing to take into account is the HVAC. The 12.1 I am fairly certain only available with auto climate. So not sure how that will work.

The easier swap is going to be 8.4 nav to 12.1

I have heard that infotainment.com is working on this and have it somewhat working.

So If I hear anything on that I will update. For the DYI it will take some work to figure out the little bugs. because there could be sales codes that have to be enabled to make it all work correctly.

Like I said the main problem being the 8.4 with nav and 12.1 having ht telematics and the Non Nav not. They do have some Non Nav with telematics as well but not sure the new ram has that option.

Nice RE: I have the 8.4 with Nav and I bought a 12.1 off craigslist for $400. I couldn't get the screen to come on. The AC/Heat worked. The sensors worked. The screen didnt. There was one too many harness wires on the 8.4. I called the service department and the guy said it's doable. But they are instructed to say they can't do it in the dealership. Help!!! Or I'm out of $400.

Heres a picture. The yellow finger indicated what plugged back into the new 12 inch nav. That last plug had nowhere to go, and thats why im guessing the screen doesnt work as it should. Spoke to an audio guy who is going to work on it for me. He said he needs to see what the harness looks like in the trucks that come with this screen as a stock and he will go from there

Any update?

You have to buy the new radio module also. You cant use the old one

This has been said multiple times but does anyone have an actual part number for the multimedia module for the 12" screen? I haven't been able to find a supplier that has any other module aside from the one that is in use for the 8.4" (PN 68307655AD). I do understand that there are differences but what gives with the difficulty to find these? I would love to do the upgrade/conversion but the RAM community is being pretty silent in regards to this.

I will try to get the part number. Even though it was said multiple times it was still being asked. I am sure I could get this working if I had a truck here to do it with. its very difficult to be confident with answers when I haven't done it yet, or seen a truck. I still have questions in regards to the connections. If someone is in Dallas and wants to figure it out Id love to work with them. Everything is possible. Just has to be figured out and work through the bugs and kinks.

Its silent because its still a new truck.

I have the Big Horn, with Non-Nav 8.4, and I just purchased the 12" display with console for $450. (A great deal) All I need is the info for the module for the display. So, I will be watching this thread to see if anyone is able to get a hold of any supplier information.

The 4c module is on ebay for about 800$. I think that's all you need to make the 12" work

The only one I saw on eBay was from a Rebel with the 8.4 nav. I believe the 12" screen uses a different module.

Update, you need to buy this part in order for the 12 inch nav to work. Even though the hazard lights wont work, everything else works.. part number is

Radio-Multi Media - Mopar (68317978AH)

Has anyone had any success in upgrading from the 8.4" to the 12"? If so, can you confirm that MOPAR 68317978AH worked?

I would like to know as well. I'm about to buy a RAM and the one that I want has an 8.4 inch screen. I'd love to change it out.

If you're about to buy a new Ram, just have it added as an option. Seems that would be the safest bet so that it is covered by warranty. These 12" screens seem to be finicky at best.

I'd tend to agree but it jumps me up to the next trim level and adds like $11,000 to option out the truck I want.

I am also interested in this. I looked at so many trucks I did not realize the one I settled on did not have uconnect. I am deciding if I want to add the uconnect module to my 8.4 or upgrade everything all together. The 12-inch screen is cool but not a necessity for me. I would however like the connectivity that comes along with uconnect. Does everyone here that is swapping already have uconnect? I could be interested in purchasing someone's module if you have to swap to upgrade to the 12-inch version that may help offset your cost as well. Also, would it be necessary to replace the overhead panel to add the red and blue buttons? My only other concern is activation. I would want to be sure that I could activate and use all of the features or it would not be worth the trouble.
