I have a HaiCOM bluetooth GPS device works great.
BUT
I cant seem to find much on GPS navigation with the Treo650 for Australia, its all the US or Europe.

If there are any Australians out there i would like to know:

Have you found any local maps (preferably sydney) that work with, Tom Tom or Mapopolis, etc?

What Navigation Software you use?
or anything related to GPS Navigation in Australia

I would love to get my Treo650 working with this so i can use it on my car and motorbike (very hard to get directions when your hands are full)

Thanx for any help guys and gals, its very appreciated
