Hello Gibson.What flavor sandisk cards - High endurance, ultra, extreme, etc? And do your cameras have parking mode enabled?
No I don't have parking mode in use as the car I previously had the F770 fitted to are notorious for poor battery life and considering the auxiliary battery unit was not on the cards. I only transferred the system to our new motor which is gifted with two batteries just before our vacation, so again still not in use yet.
Regards Max.
