I purchased from Garmin the Garmin G2 - HXUS039R-US (v11.00)
If you actually bought HXUS039R-US (v11.00) from Garmin (instead of downloading the map with links provided here at Noeman) you should be entitled to a free upgrade of that map. All BlueChart g2 & BlueChart g2 Vision with version 11.00 where recalled by Garmin. Details could be found at Garmin homepage.
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's no CD edition of BlueChart g2 charts. You may find MapSource CDs for the discontinued BlueChart (g1) products. [Only registered and activated users can see links. ]
As catymag pointed out - Use Garmin HomePort to view the chart on a PC.
It's possible to use GMapTool/cGPSmapper to make a crippled MapSource version. That needs some tweaking but it's not worth the efforts since HomePort can do it better without hours of trial-and-errors attempts.
