Garmin GPSMAP 66i and map choices

[Rokwiia]

I’m considering getting the 66i but have two questions concerning maps. It looks like it comes with 100k maps which I’m not interested in. I’d want to either buy the 24K maps or upload better maps.

1. Can you upload mapping files GPSFILEDEPOT.com into the 66i?

2. What other topo and trail maps would be there to use rather than the 100K maps that come with the 66i?

Not sure about the file depot but OnX chip has 24K maps and i am getting that for my Garmin 62s.
