Title says it all; what basic/minor upgrades do I need to do to have this thing driving at 100%? Belonged to an elderly guy before me, things like brand new still!


Also 1 thing... I tried plugging my iPhone XR in via the usb and the dash screen spazzed out and said some type of memory error (it just wouldn’t sync).

however, I got it to sync wirelessly via Bluetooth, Phone AND Music.

Are the navigation/audio systems supposed to get upgrades?
