I've written up what an Alpine ILX-107 (with wireless CarPlay!) looks and feels like when installed in a 2014 Prius v: All Sorts of Stuff: CarPlay Report: Alpine ILX-107 in a 2014 Toyota Prius v Enjoy! Short version: It works great! Very fast. Greatly recommended.
Do you know what's involved with programming the Maestro RR? I'm looking to do this installation myself if possible, and I could never get my previous radio to work with my steering wheel controls.
Nice work. I am also thinking to do install myself. Bought the entire package through Crutchfield (Pioneer AVH-4201NEX). I will be installing Axxess ASWC-1 Steering Wheel Control Adapter. Need to look for reverse and parking break wires.
Looks great, Tom. Does your bluetooth phone (and steering controls for it) and backup camera still work as before?
