Garmin XT wrong positioning for 50-100m

[gorandz]

When I run garmin mobile Xt 4.20.50 it always give me wrong GPS position which is 50-100 m from my real position.
At the same time Igo 8 runs perfectly and without problems and always giving me real positon exact in 1 m.

Is there any patch for this version or need to change some settings in GMXT.
Does anyoone had similar problems?

Thanks forward

Why don't you try tomtom 7. It works fine and it will give the right position.
