I'll check the firmware version on mine tomorrow. Just got it and it all seems fine other than the microphone seems to be very sensitive to vibrations and gives off a horrible bassy or scratchy sound compared to the AutoVox one i returned due to the date and time settings not saving.
On the audio issue I'm going to try route the wires through my trim snugly and add some more sticky foam on the mount (added some already and reduced the issue a lot) to see if it stops vibrating. Next I'm going to take part of the plastic wire casing off just to check if its possibly that rattling against the camera.
