I have a Gen 2 Touch 7 which means that I have one card slot. Is there a way to add a useable second card slot? I would like to record sonar data while using a map card in a different slot. There is a NEMA 2000 network on the boat. I know one answer is to purchase an additional Gen Touch unit and connect them but I wondered if there were other options that might be better/cheaper.
Thanks,
Anthony
