I pulled my dashcam drive tonight and found the .rec files that reside in the root directory are now viewable. Before 42.2 I could not play them. There were some .rec files on the drive when the firmware was 39.7.1 and they are NOT viewable Since 42.2, now 42.4, there have been 20 .rec files made and all but 1 is viewable. I am sure since watching them they are created when the car is turning itself off. BUT ..... since 42.4 my music USB drives will not play, the same drives I have used since I got the car, go figure.
