Comparing 8.4AN to Garmin 3590LMT
Attached are two pictures of my Garmin screen beside the 2014 GC screen while approaching the Arches Nat. Park in Moab, UT.
After driving 5,000 miles across the country, the Jeep Nav system has been "acceptable". It has locked up three times but, most of the time, it provided accurate navigation. The warnings that I am "entering an area with unverified map data" is more than annoying. I believe that it causes erroneous directions in small towns, cities, and getting to and from hotels off the Interstates. Several times, rather than direct me to turn left on a road on the map to go 100 feet to a major highway, it directed me to go right and loop through other streets to end up 100 feet to my left.
The Jeep screen colors are drab and less clear than my Garmin. The 3D view is closer to a 2D view than my Garmin but generally provides more street/road detail. However, at 60 mph and navigating to a point 10 miles away, I would rather see the road further ahead. The touch screen response times are slower than my Garmin.
