Ok, not trying to get too controversial (not saying I want the service for free, but maybe discounted... or free) but I am contemplating adding the NAV to my 8.4 uconnect in my 2017 bighorn eco. I was watching a YouTube video and a dude said that he had his done online with a radio repair shop for like $275, which got me thinking there may be a cheaper way than going to the dealership. Has anyone upgraded through any other routes, and if so, are there any pro's or con's? Also, is anyone familiar with running "lockpick" to screen mirror? Thanks in advance for any help.
