Thanks, that's helpful. I have the unit in now and am getting used to it - feedback in detail and pics coming soon. Some first impressions though.

1) Eonon logo on the unit breaks OEM look.
2) It looks great overall and perfectly matches the dash style and lights
3) Will mount without the brackets but sit a little loose on the bottom.
4) Depending on how its run, extension harness may be too short. Had to extend mine.
5) The unit is great. Android sucks. I'm an iOS user so this is subjective, but holy crap is it just an annnoying OS. I knew that coming in though so can't fault Eonon.
6) It really benefits from an LTE hotspot. Lots of OS and app functions assume always on data and don't work right without it.
