 From experience with SD cards ( sadly not the Navi GPS, but as soon as 
I'm next paid :) ) the smaller the better and branded media. I'm not 
sure why but out of all the various pieces of equipment that I have used 
SD cards with, it has been that above 512, no matter who is on the label 
it can be flaky, under that I have always had best results with the 
branded media (in my case Kingston, just cheap when I bought a load of 
them). This has been across various mp3 player, usb drives with 
expansion slot, cameras and pda's. Hopefully things are improving in the 
high price range of equipment.
