I'm looking for the same kind of thing. Garmin seems to have abandoned the off road market, and lowrance has picked up the clients. I had a ton of Garmin files and the tracks that went on them, but when my GPS Map 162 wore out, I couldn't get anything Garmin to replace it. I did find a tiny touchscreen model that had topos loaded in it, but it grew legs, and was way too small to be of use anyway.
Is there any Lowrance support out there?
