Thanks for the reply, Shane.
I should have mentionned that I already knew about Naviextras, but I was wondering if this is the only source for maps tat are compatible with iFly.
For example, Backroad Mapbooks seem to have very nice hi-resolution ground maps.
This is just to spend some time on the road with my 720, until you add the aviation coverage of Eastern Canada, and then it will be installed permanently in the airplane.
