I think not very old. Just bought new one few months ago -Navroad 320 Moto. Few days ago changes of altitude worked ok but since then i get ,,0''. Few times reinstalation didnt't help.
Are you really using the app on a Windows CE system? Probably this is a very old device, isn't it? On older devices you might only get a 2D GPS fix, not a 3D GPS fix (meaning that altitude is missing).
I dont understand what is going on with attitude in Run Gps . Maps from Mobile Atlas Creator works ok i get fix-,,good '' ( with some problems) see my position on the map but i always get the same ,,ATTITUDE'' ( for example 105 m or 0). Total ascent and descent is always ,,0''. I tried this same with track but no changes -total ascnt descent =0 . Programs reinstalled many times but still no changes.
What should i do to see changes of ATTITUDE in Run Gps?
