Just finished up the 2.5 HMI/radio/usb upgrade in my 2015 to add Android Auto, Car Play, and the in motion unlocks through @GTPprix at WAMS. The process was straight forward and easy and the results are awesome. Highly recommend doing. I did run into a hiccup on the factory nav calibration afterward but all ended up ok and WAMS was very, very fast to respond and help out.
Now to start sourcing an instrument cluster to finish the upgrade completely.
