5th Gen Head Unit

[Scaleguy53]

I have a 2022 Ramm 1500 Ecodiesel. I replaced the 8.2 head unit with Links well tablet. From the beginning, I have not been able to get backup camera to work. In addition, there was not a patch cord for the 2 USB & Aux port under the unit. Also, my intermittent wipers don't work. Dealership is blaming the Linkswell unit. My question is, if I replace the head unit with a 12 in unit from a 5th Gen, will it plug and play? Service advisor at dealer said no, that vehicles are being built that you can't change/upgrade them. Does anyone know if that is true/ offer advice/opinion?

Since every item that's plugged into the canbus system is also programmed into the ECU of the car it will only work if it's (re)programmed in the car's ECU. I changed the middle console with OEM one with wireless phonecharging doc. It didn't work until after it was programmed into the ECU.

I went with gen 6 Linkswell in my gen 5.

Actually, all that programmed stuff is in the BCM (body control module).

ECU (PCM and TCM combined) is engine / transmission only and not accessible to the little guys without a tuner, Unless you are using something like AlfaOBD or a scan tool to just test certain components..

Try another dealer (may be difficult since you show you are in Mongolia).

@ GlobetrotterV8 is partially correct in changing the configuration to get some optional functions / equipment to be recognized and operational. That is done in the BCM using something like a scantool, or the much cheaper route is to do like I do, using AlfaOBD software (phone / tablet or windows PC type. I use it in a windows 11 PC and works awesome). You will also need an OBDII dongle to allow the program to talk to the BCM and it needs to be a good one that is Bi-Directions comms capable. I use the OBDLink MX+. This combo has never let me down.

Your truck being a 2022 will need a security bypass cable, also.
