You might start at the website for the card support your Garmin uses (i.e. c-map, Navionics, etc.

I think Garmin uses their own proprietary technology in their cards. According to the info I have from West Marine the unit you have uses the SD card type. Also according to my info the Garmin card #010-C0894-00 looks like it might have Lake Martin. I would give Garmin a call and verify or ck their website.

We have a Navman chartplotter on our boat and were able to get a nice card with Lake Martin data. It works great. Some of them don't have depth contours so watch for that. If they use USGS data it may not have contours.

Good luck!
