Unfortunately I have to report that this application lags BADLY behind the actual position. I have seen it do the same on my colleague's WinCE device and also on my friend's 5800. Actually, it is better on the 5800 - side by side I had 22m accuracy and he had 11m. Disappointing, to say the least. Ovi Maps is spot on on the 5800 so it can be done and the problem is the software...
