The cameras come up a bit larger than they did stock, and the backup sensors have a much larger display underneath the camera view as well. It seems to take slightly longer than stock for them to appear though.
I messed around with mine a bit more tonight and have realized that I'm not getting any sound from anything on the tablet portion. Waze, Spotify, the music player, etc all appear to be playing but no sound is heard. I thought I had been using Spotify on it yesterday but I think it was actually coming from my phone through the SYNC bluetooth connection. I'm definitely going to have to put a call in to Phoenix tomorrow.
