I know that is an older thread but since it is still active and it appears that there are several knowledgeable members on her I present my issues. I have a 2021 Ram 1500 DT Bighorn which came with the 8.4 non-nav radio and dual zone auto HVAC. I bought a 12" UAX kit from Carplaynav.com in Canada. The kit included the screen, module, video cable, an adapter cable and on a loaner basis a tablet with AlfaOBD, security bypass and OBD2 Bluetooth dongle. Had to give them my VIN for programming and have the Sirius option.
I installed everything and set the ISC to not enabled and the DCSD to enabled (per the instructions and as it is also mentioned here). I let the truck sit overnight, also disconnected the battery a few times. That was about three weeks ago, since it takes some time for everything to populate.
I still do not have a back up camera. When I put the truck in reverse the screen does not change, when I use the Rear Camera soft button I get a blue screen on top and Control screen on the bottom. I know that the system is capable of displaying the camera view because after the truck is parked for extended periods and I start it and put it in reverse really quick it displays the rear view, however, hitch view button does not work.
Other issues are that the Sirius Travel Link icon is missing. Also, the GPS is spot on I can only search for addresses via voice; using the keyboard gives me error messages. Lastly, not sure if that is an issue, I thought that the HVAC hard button on the side of the screen should be backlit during the day? They are at night with the lights on.
The vendor thinks that there is something wrong with the module and will send me another one once they get on.
Sorry for the longwinded response but I wanted to detailed, hoping that somebody can shed some light on my problems. I have my own security bypass, tablet with AlfaOBD and a OBD2 dongle.
Thank you in advance for any input/advice.
