Android / Premium Retrofit MMI
OK, I'm seeing a lot of chatter, but not really the info I'm looking for specifically...
I'm interested in adding Android Auto to my 2015 REX. Premium Retrofit seems to be the general favorite in here, although BimmerTech has some fans, too. A few people have mentioned RoadTop, with decent results.
All I really care about is integrating maps on the screen and maybe a better music app. I could see adding the backup camera, too, as that would be handy. Ease of installation is also important to me, but they all look very similar. I don't want to have to worry about any of the existing tech getting screwed up by the process.
So, RoadTop is $200. Premium is $400 (plus $100 for the camera later). BimmerTech is $700. (Unbranded options are ~$150, but that seems risky.)
Am I missing some pros/cons to the different models? Is there another brand I should consider?
