I installed the 12.1 inch Phoenix into my 2011 crew with Sync 1 Nav at lunch today. Pretty simple install except have to partially remove the passenger airbag module to get it in but worked it out pretty quickly. Works great, Sirius works, climate control works, backup camera works. Haven't tried all the many apps on there yet but the stock functionality is there and the screen looks great. Bought the Apple Carplay / Android Auto option and will try that tonight or tomorrow after work.
