They may work well in (relatively) densely populated areas like Britain, Europe and much of the USA but beware when travelling in Oz. Around the suburbs they're fine and they'll get you from Adelaide to Darwin just as well as any road map (vice versa is also true).

But if there is some bush track that goats use to cross the ranges and it's the shortest distance between your start and end points, make sure you have a full set of outback recovery gear on board. From New England to Canberra, most digital maps take you over some very crude tracks through the Liverpool Ranges and they're not for ordinary cars with a load of kids wanting instant gratification at O'Donald's. A recent case in Victoria found a car stranded in floodways because the GPS said that was the way to go.

All grist to the mill! But not what you want either immediately beore or after a gig.
