I know some other UConnect 8.4 vehicles have map upgrade procedures figured out using standalone Garmin GPS units. Has someone figured something out for the Journey? My wife totaled her 2016 Journey out this fall, and we ended up replacing it with a 2018 with an 8.4 UConnect with navigation. The 2025 map update is the last one that will be provided for it, and given that it doesn't even have 50,000 miles on it, I'd like to keep updating the maps on it for longer if possible.
