I was at a store in Albany last week and was told the only way to get Streets/Tracks/Topo was to send my card to Next Destinations and they would do it for around $150.
I insisted that the 600 has an SD card and as the proprietor had a 600 sitting in a box on the floor he checked and apologised.
So the option is there to purchase the SD for $299 (better than the $399 they were).
I can't find any reference to a card modification on Next Destinations site, so, is it an option or a Furphy? If it is (an option), is it worth stuffing around to save the $150 (not that I want to throw it around)?
