Folks, putting the benefits of one software or the other aside, the V2 or Gliderguider are just great PNA's. I have flown with a V2 for the last two months and the visibility is excellent, under all lighting conditions. I used to fly with a MIO400 with a sunshade and the V2 brightness is night and day. I understand that the V2 can run several type of softwares (XC Soar, LK8000, SeeYou mobile, etc).

The 5" screen is large enough, but not too large to fit on the side of the cockpit. These PNA can also connect to other instruments (e.g. LxNav V7) via bluetooth.

The price seems about right for the visibility. Other soaring dedicated PNA run over $1000 (LX Minimap). The Oudie 2 seems to be a similar hardware running SeeYou Mobile. So, for the purpose of comparing the V2 and Oudie, I would argue that these are essentially the same (except for the preconfiguration that Oudie offers). There might be Android hardware solutions out there but the only software option at this point is XCSoar.

My 2 cents.
