So - now it's a year+ since the last post... I have a 2012 X5M and I want to do a head unit upgrade this Black Friday (this week).

I have looked at both the AvinUSA and Xtrons web sites, and they seem to have similar products. The Avin is well organized and it's pretty clear what's what, but the Xtrons web site is a mess - I still can't figure out what is different between the various models for the E70. I've read a couple of posts on forums from people who have had issues with Avin.

I am only interested in Android and Android Auto - no Apple users here, so I couldn't care less about any CarPlay issues.

Is there anyone out there that has experience with Xtrons or Avin head units in the E70? I'm looking for feedback from people who have done this upgrade. Thanks.
