I was wondering if anyone could help me with putting the bluechart g2 canada maps on my Garmin Oregon 400t. I have read lots of post and have downloaded lots of software, but I still can not figure it out. I have download some bluechart g2 canada maps already (gmapsupp it said it was unlocked, there was 3 parts to it, used winrar to make all 3 parts into 1 file gmapsupp.img) Now, I am not sure what next. I have mapsource, fast img unlocker, home port, mapsettoolkit, and well I am very lost. Any step by step help for the GPS would be great.
