The map was cleared from the GPS when I updated to the most recent Garmin software, that is what I meant when I said, "I recently updated my Garmin Echomap 74dv."

I am using a PC. If I know what kind of information you needed I may be able to tell you.

I have the map you referenced on my computer but don't know how to get it to my gps.

I can see the map in Homeport but for some reason I can't transfer it to my Echomap 74dv

I don't think that I can use Mapinstall because I do NOT have a hard connection to my gps I have to transfer maps by a memory card.

I have the maps that I bought from somewhere. The file name is "123-9888-fltopo_gmap_install"

I don't remember how I installed them. I have used homeport for marking waypoints etc.

I'm sorry if that doesn't help

I recently updated my Garmin echomap 74dv. Now I can't get my Florida topo maps back.. I'm not real good with electronics anyway.

I use the Garmin Homeport program for my maps

Thanks for your help.
