..... OEM Nav is years out of date with a new purchase so there's no point in using it. Anecdotal, but at least for my town (outside of Memphis) the OEM map has less than 50% of the streets.
**At least with Uconnect 4.
I've never had a single instance where my OEM navigator didn't have a road I was looking for. I should note that Ohio is pretty rural, and even the "big" cities in my area are a far cry from Memphis, so roads aren't added or eliminated very often. It's also worth noting that I used it to get me to just outside of Pittsburg to pick up my Rebel wheels/tires and it navigated that just fine. That concern may be specific to your area, or major metropolitan areas in general.
I've had OEM nav on all my Rams and Jeeps since 2014 and have had zero issues. In fact, like it so much, navigation is a must have item on my purchases. I pass on a truck once because it didn't have nav and the salesman tried explaining the "convenience" of Android Auto and Apple Car Play. He obviously ignored the fact that you have to have cell signal for those to work,
and you have to have your phone with you, which has to have data. With OEM nav all you have to have is the antenna accessible to the gps satellite.
For the younger generations, AA/ACP may be the way to go. It's not for me though, I'll stick with my built in nav. Which btw you can update if your maps are out of date.
