Similar to iTreks

The price is outstanding - and with A30 updated w the new ROM A05
it seems to work even better.
I have not seen a good comparision w this product - yet.

To most important choice is the SW.
I finally chose the Destinator since BuyGPSNow had a great offer
and that I could get US and Europe coverage. Otherwise the iGuidance seems to be a good choice as well.

If you are planning to go hiking you can always try/use
https://outdoornavigator.maptech.com...ator/index.cfm
that works great for US.
In Europe I have not found a similar product - perhaps VITOs
Navigator 2 or Smartmap

The maps can be bought online there or you could make your own
w their free Mapmanager
