Thanks all for the helpfull replies ,Ive only use the navman when i,m in adelaide but you dont really need one there because if you get lost there you just stand on the roof of your car and you can see the city.
Space aint a prob since i,m in the 2008 V8 landcruiser ute but i,ll have to hurry out of there and get back over the mountains to beat the rain if any...........but seriously i aint going that far to go home empty handed.........cheers Kev.
