GPS loadable maps

I forgot to ask, are you using the 64 for vehicle navigating or walking. If for vehicle get the Nuvi 2797. 7inch screen lots of info and costs about $280 but you do need to add the topo maps

I have both Oztopo V8 and Garmin TOPO, plus Shonky Maps, they ( TOPO's) are both good but you can do routes on the tracks ( Dotted lines ) on the Oztopo V8, but not on the Garmin TOPO. Other wise they are all good gear ,
Cheers Des.

I would love to try out Oztopo but its a lot of money if I don't like it . I usually create .gpx files of routes on Ozi pc and transfer them to the Garmin Nuvi via usb connection .Problem is the gpx file can't contain many points otherwise it won't be read (unlike the Zumo 62/64 ect so have to make a series of small files. For trackless desert nav and in 4x4 mode its a fantastic device for plotting a go to as crow flys by just touching the main nav screen then touching where you want to go by scroling to a point then go to.Of course i use it in conjunction with Ozi Android that I preload it with routes on pc or create points enroute .In June this year I used my Nuvi as a test with OSM free maps preload at home with the Madigan Line waypoints and a route of complete track and the nuvi actually guided me to Birdsville from Mt Dare .(not recommended for learners) The OSM map also contains Steve L 2006 Trackless Geo's route line crossing same as on the NT EoTopo sheet. 'Hope your getting royalties Steve'

Thanks to everyone for their input. I'll have a look at the other options raised before deciding.

I'm only considering the GPS for bushwalking at this stage, not as a dash mounted unit for vehicle navigation.

cheers
