I just had Android Auto installed by the lovely people at StageX in Coventry. They opened up specially on boxing day morning to do the install. Highly recommended. I also bought an AA wireless dongle which now automatically connects my phone wirelessly to the ICE system. All stock parts, just a quick software update on a 2015 RS-275 Nav to bring it bang up to date.
Had this done I while back through Stage X as well as having the RS monitor enabled. Waze and Spotify are the apps I use most, very handy. I'll have to get a wireless dongle too.
