Hello everyone, I need your help, I have ram 1500 2020, uconnect 8 was standing, I decided to upgrade to 12, bought a control unit and a screen, changed the parameters via alphaOBD, but nothing works, the screen is black, maybe I bought something wrong, please tell me

You also bought the screen for 1500 uc5

Now I have put another control unit, the screen has turned on, but the sensor on the screen does not respond to finger taps

 

[Di54]

The sound is there, the modes are switched, everything seems to work, but it does not respond to screen taps in any way

I’ll send you a PM. I build mine so you don’t have to tap into any factory wiring.
This is the solar sensor you need- 68230114AB
Cabin temp sensor- 55111178AC

I need one of these harness, how much?

I don’t know if I had lucky but I bought I UC5 12.1 screen I bought all connectors because I used to have UC4 8.4 non nav … the thing is I didn’t change anything in alpha OBD and I soon as I putted ignition on the radio started and everything worked great , ac, cam etc but the only thing is the radio profile is locked .. my question is how can I reset the radio…

 

[b4ville]

Well ..I resolved my issue, I paid 8 dollars for lock pin on eday … now the radio works flawlessly ….

Hi all, just bought a 12 inch uconnect 4 system for my 2020 big horn. Coming from an 8.4 non nav. Want to make sure I have everything I need before I install because I really don’t know too much about this lol. This is what it comes with. I know I’m going to have to buy the programmer.

I dont see a repin harness and for some reason you have a uc4 to uc5 and then back to uc4 harness which is not necessary. I'm not 100% on what fakra lvds cable you have but as long as it is a normal one and not the uc5 lvds cable all you need is a repin

I have UC5 , I can’t find any updates I’m running 26.17

I have UC5 , I can’t find any updates I’m running 26.17

26.17 is a current uc5 file

 

[b4ville]
