Wow thanks patio, that is exactly my model.
I would truly just buy a new one with todays maps if I could find this unit for sale with 2011 maps. I'll scour this site and see what bounty it brings.
Imho they are the best unit i have ever used and address all the requirements that suit me for navigating in Australia.( They do have some drawbacks though, such as the thickness of the unit, but I can live with that for now.)
Mind you of course, I dont have an Iphone or a HTC or similar either.
I am certain there are lots of better units, phones, call plans that provide a phone and all sorts of other ways to update.
It has cost me a small fortune buying one, not being happy with it and selling it on to someone else and committing to another for the same result.
I think I am up to my ninth purchase of new products, so I decided to stick to this one.
Thanks for your assistance.
Baby steps for this budding techy.
