Hi just got this older unit installed on my boat and all is good. Has a west coast map card in it and everything works.

I'm a bit confused about the recording to the card function. If I decide to record a map track will I need to take out the map card and put a fresh one in or will it record to the empty space on the map card? I can copy the map card to a larger capacity micro SD to make more room if necessary.
