I was just looking on Ebay, and I see some 7" and 9" CarPlay screens that hook up to your phone, and it charges your phone while it uses it for the navigation. $100-$125 and most will connect to Apple or Android. They also include a backup camera. Will allow you to play music from your phone through bluetooth as well.
A mount that would hold the screen on the back of the glove box door, flip it down and when you're done close it up in the glove box. The mount would face the driver of course.
If you own a show queen, this is probably not a solution for you, but then again, you won't be driving your truck much if it's a show queen so you probably don't need navigation.
