Avin Avant 2 Universal 7" double DIN Android radio likes and dislikes

I really like this radio, but here are a few of the stand-out likes and dislikes for the Avin Avant 2 Universal 7" double DIN Android radio. The non-universal Avant 2 (for BMWs, VWs, Hondas.....) will have slightly different features, but should be very similar to the universal.
Thanks to PMitchell1063 for summarizing the points with times.
