I got a Uaq from a g-56 18 truck coming to try on my 14 g-56 truck
Back up camera don’t worked it was manually activated.
I could get the bcm too
The BCM appears to be the same as all other 18s
I will get the vin of the Truck
So u can See if they have a different software do to the g-56
Camera works perfect with ra4 installed

Does anyone have any idea what to do with this or did I just brick it by trying to update it? I got the file from the dealer to 22.6. It sat on this screen for about 10 mins. Then tried to reboot the. Stayed stuck on this screen.

When this happened with my RA4 I just left the update in and walked away. After a day or so the radio booted up successfully and installed the update.

Do you know what part/section the radio failed on?

Mpgrimm2 Do you know if the BCM would be compatible
Figurine one is a 14 and one is an 18 but they’re both Cummins g56
They want to hundred bucks for it which I don’t have any problem spending

I don't know where it failed. It intially said 35 mins for the update. I came back 5 mins later and it had that failed screen and said it would revert to the previous software update, it stated on that screen for a few mins then said update failed again and gave the Error 20 Code. I took it to Dodge and called Uconnect and they both made it seem like I was SOL.

Two questions, have you let it sit with the update in for any amount of time (like 48 hours) and are you still within the return window? Sometimes it's best to just cut your losses while you can (a lesson I find hard to follow)...

I unplugged it and removed it from the truck because it stayed on that screen even with the truck off. I am still in the return window so was thinking of just doing that.

Understandable. If you have the time, just leave it in with the update USB and see if it revives itself. It seems on the older units, if one section failed it would keep retrying for a long time but it eventually timed out and booted up again. I know these are different hardware but the firmware software design may have been created with the same failsafes...

Most likely not.

Your best bet is to find someone with a 2018 g56 truck And the 8.4 that can either readout and share their stock BCM config from AlfaOBD or that will let you pull it yourself.

M² Mods.

The connectors are the same
Is there a way you could look up the pin out and make sure that’s the same
The part numbers are different however

Quick question, is there any way to identify a UAQ vs UAS in equipment listings? Everything i see on window stickers just says "UConnect 4C w/ 8.4" Display. In other words, how does Ram show it has NAV (UAQ)?

Edit: another question, anyone ever had their free SXM subscription disappear? Mine was good until 7/23/2020 and now it says there is no subscription.

I'm fairly certain the build sheet or window sticker will say GPS Nav as a separate line item. Can't help you on the SXM issue.

That's what I thought too but I'm not finding that to be the case. Would anyone with a known source VIN for a UAQ PM me the VIN?

I just want to see if there is something that identifies it as such on the build sheets and window stickers.

Here’s one that’s for sale with the UAQ:
https://researchmaniacs.com/VIN-Num...ker/DodgeSticker.html?title=1C6RR7JT9JS192885

Look at the item that says:
UConnect 4C NAV with 8.4
That’s what you’re looking for.

Perfect! Exactly what I was looking for thanks!

I'm finding that many of the salvagers have their UAS radios listed as UAQs which is why I couldn't find a difference in the build sheets.

For anyone wondering, a UAQ will explicitly state "UConnect 4C NAV with 8.4" Display" and "GPS Navigation" on both the Window Sticker and Build Sheet...

Here is a link to the build sheet for the above truck.

https://www.ramtrucks.com/webselfservice/BuildSheetServlet?vin=1C6RR7JT9JS192885

Under "optional Equipment" it lists;

* Uconnect 4C NAV with 8.4" Display

PS. You can put in the VIN of the donor vehicle in place of the example VIN above. If you keep looking you will find a UAQ that is priced like a UAS from the recyclers. It also helps you avoid the other scenario where it is priced like a UAQ but it is really a UAS. Also, ask them if it includes the bezel. Some with throw it in since they really don't care about recycling "trim" pieces. To those of us doing the upgrade, that is like $100 part.

First post here. I've been watching a few threads for a while and have a question. I have a 2018, 2500 CTD, came with the 5" radio and 4 speed fan. I have installed a UAS and it works fine behind the 5" bezel, but want to complete the upgrade. I already have the 2018 HVAC module, USB hub, and single zone bezel. If I'm understanding everything, I need to order the 4 to 7 speed conversion harness from M2Mods. Do I also need to order the 4 speed fan motor/resistor harness? Can someone confirm this? Thanks for your assistance and all the good information.

Just contact MPGrimm2 (Mike) at M2 via PM and he will go over everything you need. It is really the best way to make sure you have everything you need for a painless install.

@Mpgrimm2 will be able to hook you up.
