I was hoping to give some good advise instead of still looking for some. I have a 2019 Ram Bighorn with uconnect 8.4c no-navi. I am trying to install navi with 12.1 display. Bought new module #68307655AD from Factoryradioparts. Supposed to work on 8.4 and 12.1. Bought 12.1 display from craigslist. I installed the new module and plugged up display as per wire connector colors. Turned on and nothing happened. Read some more info in forum and found i needed an LVDS cable. I looked all over America and finally found one. Got it today. (SO EXCITED) Put the muti-media module and 12.1 display back in. Turned on and the emergency flashers came on and would not turn off. A gain. Not really because still no screen. Module came with code but can't put it in with no screen. I would appreciate if anyone is having any good luck at this yet to please let me know. Thanks so much.
