Yeah I have the same but some of my files are huge though.
I've got a City navigator 2015 that is about 130 MB but I've also got A&NZ Topo v5 that comes in at a whopping 4.2 Gig!
I've also got area specific maps that I have tiled off Mapsource using NEMA raster maps that are between 20 and 60 MB. All are *.img files and it seems that the Topo maps be that Garmin, HERE, Sensis, Navionics, Oztopo or Bluechart seem to be just getting bigger and bigger! My 32 Gig SD card is getting rather full.
The Etrex 10 and 20 have the super slow and obsolete USB v1.0 as a way to get user to buy the better product the Etrex 30 but due to the horrendous policy of Garmin's use of buyers as Beta testers for early firmware versions, some like me just wanted a device that worked rather than having to endue years of buggy firmwares before getting a working model finally and not surprisingly right before the release of an updated version with an updated price to boot!
So after all of this, if Garmin forgets to update it's processor to handle the better graphics and retains it's useless obsolete USB v1.0 as standard then my advice to buyers considering the new Etrex 20x/30x would be to stick to the now much cheaper Etrex 30 and don't waste your "hard earned" money on the new Etrex 20x or 30x that offers not much more than a BIG price hike...
Whoa, maybe there is brandy in brandy custard after all...
