Garmin gps model difference and other things

One other thing,can they all be carried around and used while your walking?

G'day Ross, I have a Nuvi 760 I use in varios cars daily, I have 2 quality velcro dots on the back of it (10c size dots from Bunnings) & I mount it in the centre of the steering wheel on each of the cars, nice & close - easy listening as well, sure better than on the screen! see yaa, aussiedingo

All the Nuvis specialise in the city but by adding Garmin Topo Sd card , you can add topo maps.

I am in Alice Springs at the moment and am pretty impressed by my new Nuvi 250 and SD card although I must say that the maps of the Donahue highway seem quite old as often my car appeared to be travelling cross country , as I assume the road alignment had changed.

The maps in the Garmin Topo are HEMA and they are very clear to read, as they have a white background with direction route in magenta and tracks in black, streams in blue and topo lines in brown.

I also have had trouble convincing it to accept a route to Alice from Boulia across the Plenty rather than through Mt Isa, however once you drive the "wrong" way for a while it chucks in the towel and agrees with you.

I am stilll learing how to overcome the limitations of finding a town where you do not know any street names! However yesterday I found that for small places all you do is enter the town and press done for the number and street and it will suggest a street in the town.EG Boulia.

Hi I have a 760 and find it great, you can use it in what ever car you like, you just have to take the mount, cord and unit with you.
The main diff between them is , the 760 has Blue tooth and FM broadcast, which is great if you are a bit hard of hearing as I am, it speaks thru you car speakers, and if you have blue tooth on your phone it lets you answer calls etc on its screen, handy.
And with the 760 you can make up you trips /routes on you PC and transfer them to the unit, it also has a track logs , which logs where you have been driving and you can download them to your PC and view them on Mapsource.
Great unit( I also have a Tom Tom)
Cheers Des.
