Seems there is some conflicting advice floating around as to whether to use exFAT or FAT32 for larger capacity SD cards in the Mobius - am more than a little confused now!!!
Must say that I've had no problems with the 128GB SD card formatted FAT32 fitted in my Mobius, which incidentally has been in nearly daily use since Oct 2014 (so almost 10 months) and it has automatically looped round on a regular basis when full, and records over the older clips because it is set to record continuously when at work, using an external power-pack to power it, rather than hard-wired, because I use it in several cars.
Settings for the Mobius are: video clip length 3 mins, video data rate HIGH, frame rate 30, video resolution 1080p, video time stamp ON, Audio ON, WDR ON, video file type MOV.
Is there any particular reason why the Sandisk 128GB card I'm using shouldn't be formatted FAT32, or is it simply because so few users are currently using larger cards that the developers have little information to go on when providing recommendations?
