I looked and couldn't find a post addressing this. I recently upgraded from uconnect 5.0 ra2 with xm to uconnect 8.4 ra4 and cant seem to figure out how to get the navigation to work. It shows me about 1000 mile away in Quebec and the gps is showing no signal. I added a gps antenna to the pink fakra on the back of the head unit and it still won't work. I have a white and yellow fakra connector and added the pink. Any help would be appreciated.
