Xtrons PF75ATTAR - a few minor issues... anyone experience anything like this?

A few weeks ago I ordered this unit direct from xtrons, and just tested in with a bench top power supply. It's running lollipop out of the box. This weekend I finally got around to installing it into my car. Everything works great, minus these issues:

1. There doesn't seem to be anyway to remove paired bluetooth devices. There's no gear cogs for each listing, and holding down on the device doesn't give you any options to remove or forget the device.
2. The Xtrons OBD2 dongle pairs with the head unit, and a blue OBD icon appears in the top status bar, but both Torque and Dashcommand see no OBD2 dongles.
3. When in the radio app, it will display the station and volume on my cars dash board (via canbus). But these messages don't always update, and get stuck with stale data - like after exiting radio app, whatever was last displayed will be stuck there. Also the volume adjusts don't update when I adjust them... it seems random... but when the radio app changes stations, it seems to work correctly.
4. Radio reception isn't as strong as my stock radio. Which is fine... it is what it is, but would be cool if it worked the same.

Other than those things I'm pretty happy with it.
