Hi, I purchased from Garmin the Garmin G2 - HXUS039R-US (v11.00) on microSD and want to load into Mapsource so that I can combine other maps into a single gmapsupp.img for use on my GPS. Although Garmin sells the G2 charts on CD, microSD and datacard, only the CD can be used in Mapsource (I didn't realize this when I bought the microSD version). There are various postings for using GMapTool to split the image and load into Mapsource. I've tried this with the Bluechart G2 and something is not working. When I attempt this, the Mapset name is in Mapsource; however, only partial charts mapping symbols are displayed. Is there a special procedure for splitting/combining the Garmin Bluechart G2 (I've looked and can't find). Thank you
