It's possible to view as many marine IMG files as you have room for on your memory card or USB stick.

Marine units and BlueChart compatible units shows marine charts with correct marine colors. The other units like nüvi for car usage & StreetPilot plus software products GMXT and GMPC shows water areas in quite dark blue. There's also lack of details for spot soundings and other marine chart details (tide water etc.).
The newer BlueChart g2 Vision v11.50 from 2010 are hard to use with GMXT & GMPC. Guessing that it would be problems with road navigators also.
.......................
It might be sligtly better results with BlueChart g2 Vision in some of the Garmin car navigators. The color palette will most likely be wrong anyway and it's not easy to correct with TYP-files.
Some units (GPSMAP 620/640 & nüvi 5xx) can switch between car mode and marine mode and show a correct marine chart in the marine mode.
