I have a gramin gpsmap76Cx. I shared the android rooting just to share that I am somewhat technical.
I think I am making progress, but I need a bigger SD card. The one I have is only 2GB. How large of a card can I use and can I load more than one GMAPSUPP.IMG on an SD card so that I can have a marine map and a city navigator map?

not all the devices support more than 1 img per sd , better to have more than one sd (2 or 4 gb sd are cheap) and swap them when you need

Do you know if I can load this map into Mapsource and then choose which areas to put on the SD card?

no you cant, this is an IMG and then you cant see bluecharts in mapsource
It will require a UNL file to be viewed with a Garmin GPS.
As with all locked g2 & g2 Vision maps, it can still be viewed with HomePort without being unlocked and/or needing a UNL file.

OK. I now have Homeport dowloaded onto my computer and HXUS039R_V11 downloaded through JDownloader. How do I get these files into Homeport and into my GPS? Thanks again for your help.

you must put the IMG file in an sd inside a Garmin directory, homeport will retrieve it, to see it in your gps you'll need to add an unlock file as explained in post 9

There are three files in the original post. Each file has an IMG file inside. I would assume that I just select the one I need for my area or am I doing something wrong? I used IZarc to open the files. Opened, the files are all larger than 2GB.

no it's just one file splitted in 3 part - use winrar and click on part 1 it will extract all the parts in one IMG
Code:
http://www.rarlab.com/]WinRAR archiver, a powerful tool to process RAR and ZIP files
the file is 1.38 gb splitted in : 512 +512+391 mb

I really do appreciate your help. When I use WinRAR, the file becomes 2.172 GB. Guess I will just go buy a 4 gb card unless I am doing something wrong again.
