Ok i'm not the sharpest tool in the shed so go easy fellas. I just bought a magellan explorist 510 from ebay.......:huh Should i just throw it in the bin or what? Cos i'll be buggered if i can find a ozzie tracks map on sd card. A bit of research may have been the go i guess. I saw a magellan xl for sale on here with dast on it....but i can't find it again now....would that also run on the explorist? Any advice will be taken even if it's to take a hike with your new magellan.
