Thanks John, I just got off the phone with Garmin, they said it had a 2056 map limit, which means I could put all of the us street maps on one card or europe but topo has over 5000 maps so I would have to split it between cards. So I guess the up side is you can have US or Europe maps which are under 2056 on one card but Topo would take 2 discs for the whole country. AT newEgg the prices for micro SD's are cheap thank goodness. Well it's still not too bad to work with I guess. I see some things of garmin never change.
