20 Most Recent Garmin GPSMAP 180 GPS Receiver Questions & Answers

I have 2 data cards for Garmin gpsmap 180 and working well.I got this offshore boat from Tallahasse 3 wks ago that has a built in Garmin gps 180 with 2 data cards on it and I have no use for it because I have the boat in Texas now. Don't know if this is the right one that you need, all I know is that these 2 cards are programed for Florida gulf.I can ask the previous owner of the boat about the details of these 2 cards. I'm willing to trade it for a data card for the lower gulf preferably from Brownsville, Tx. to Louisiana or anything that will cover Port Isabel, Port Mansfield, Port Aransas.
