Looking to replace the 7" screen with a used 8.4 w/nav. Found plenty, used and reman'd, like infotainment.com. (Not willing to pay $1,400 at this time)

Only thing I'm concerned about is compatibility. How far back from 19' can I use used 8.4 units? New T/A has performance package w/pages but the 7" screen, so yeah, I need an 8.4.

What I'm looking at:


  • Radio - Audio Video Equipment RECEIVER AND DISPLAY, 8.4 TOUCH SCREEN, W/NAVIGATION, W/SATELLITE RADIO, W/TELEMATICS ID#68258397AD

Do you want AndroidAuto/Apple Carplay functionality? Pre-2017 radios don't support that, so if you want that functionality, you need a radio from a 2017+. Also, for the 2017+ radios, there are two different radios - a UAS (non-Nav and cannot be "upgraded" to support nav) and UAQ (has Nav).

You have to be careful to get a UAQ unit if you want the nav functionality.
