Next April we will both be retired, and plan an extended ( 6-8 wks ) ride around central Europe ie Hungary, Slovakia, CZ Republic, Poland, and possibly into the Ukraine. We are looking to take as much info as possible on the Zumo to help with finding hotels, campsites etc. Can anyone tell me what is the largest sized SD card they are using. There's lots of posts re 4 Gig max, but some peeps seem to be using 8's and there is a mention of a 16 Gig card being used. I would be very grateful for your help in this matter, and also for info about POI download sites. Many thanks in advance.
