Yeah, there is a few devices advertised for like $110.00 more or less that U plug into yer USB, then link with yer phone to run all functions off of phone. If I was using my truck a lot to travel and whatever, I would use instead of plugging in cable. MTNRIDER correct, it all depends upon what radio U have in dash. There are like 4 different types, with a lot of the Bighorns (I have a MY 19) having a U Connect 4 radio only, plain jane, No NAV/GUARDIAN/911 STUFF, ALSO no OTA upgrades/updates, dealer only. U can also get a plain jane but HD radio, Radio with NAV, Radio with NAV/GUARDIAN, etc. Just kinda depends either how U order or what was on build. I do not need my truck to call 911, or use the outdated (IMHO) RAM/FCA Nav, so I use my I Phone for Maps, or Google Maps or Waze depending upon where going. I even wired in a Bluetooth capability into my speakers and can set I Phone to run on my Motorcycle ref sound.
But again, back to the OP and this thread, all depends upon wat Radio in truck.
In MY 19, there were 4 radios possible: U Connect 3, Uconnect 4/4C/4C NAV. I read there is a U Connect 5 out, not sure if in the 21's or the 22. SInce I have a MY 19, did not interest me.
