C'mon Paul. It's not exactly a big place. You can't get lost. Just follow all the other nutters out of Douglas and 20 minutes later you'll be back in Douglas again.
Er its not big enough to map. Do the TT course and you`ve done the island. Calf of Man to Point of Ayr I think you could walk in a day....or am I being silly again?
Howard & Dave, it's difficult to get lost on the circuit but I always take an OS map for the more interesting bits like green laning. It's an offroad paradise. I got the GPS because I also find he streetlevel mapping useful and it's easier to follow than to keep stopping to look at a map.
Markie, I was looking at the Garmin site at the v.6 and was hoping someone had a copy. It's not worth the price just to get the IOM as I've currently got the Europe Metroguide v.4 with all the upgrades to v5.4
