Also I am looking at the maximum card that can be used in the Garmin 55 camera so thanks for the question and answer. On larger cards does any function slow down? maybe playing back videos in the camera slower seeking? any painful constant warnings come up from this ? It does seem strange to just blindly say only 8-64G is usable. manufacturers treat customers as crap really.
The aussie original 8 gig card even at the lowest resolution doesnt record very much ( not enough for a long trip recently after getting the camera and we lost the one incident that i assumed would be saved. I pressed save down the road a bit but it was way too late. Seems it really does record 1 minute video as normal!
that shoould have been a lesson to stop and find the file to be saved however thats counterintuitive to safe driving practices.
