Navigadget: TwoNav Aventura is a new handheld GPS navigation device that is quite different than most other handhelds out there. It can accept any kind of maps, provided you are capable of creating vector maps and raster imagery. You can even scan your own according to gpstracklog and calibrate it to use on TwoNav Aventura.
Another feature of TwoNav Aventura (perhaps where the “two” is coming from) is that it can also act as a GPS navigation system for your vehicle, giving you door to directions.
Apparently it is being released in Europe this June for 650 Euros [...].

* Li-Ion battery
* Battery slot can be replace with 3AA battery slot
* Up to 20 hours battery life
* electronic compass
* barometric altimeter
