i have ordered the garmin drivelux 51 lmt, its the latest and best ( well, most expensive in the car range @ $500). yes, i,m serious about not getting lost again. it has many features and can download outback bush tracks, treks. garmin says it works off a different signal band/system, i hope it goes good in town too. i,m looking forwards to getting it.
