Well, so I tried installing Smart2Go maps on my Wi-Fi enabled Mio P550 .... installation was fine (fine = as reported by a gang and grip of other people, I could not even download the installation cab file via the IE browser on the PDA, since the "download" button does not work on the PDA -- I had to download it via my PC and then transfer it to the PDA via Bluetooth).
I established my Wi-Fi connection on my PDA, and then surfed to Greece to check to see if it worked -- NOPE. Never got anything. I only saw maps seemingly work for Italy and Germany -- I waited like 30 minutes, and maps for Greece and the Czech Republic never came up. Great stuff.
Then silly ol'me thinks that, I'll just use the MapLoader to load up the maps. So, I download the MapLoader that Smart 2 Go offers -- but *naturally*, I could not get the MapLoader to recognize my SD card in my card reader, nor could I get the MapLoader to reconize my PDA as "USB Storage." Complete junk.
I'm not the brightest bulb in the bunch, but I really couldn't get it to work -- it got uninstalled. Not to "smart" Smart2Go ... not to smart. You guys might want to really focus on usability and actually make this stuff work.
