I have some problems with the Route Magnet feature. It looks like that the magnet is not properly sticked when set. Quite often the Route Magnet has not any effect to the calculated route at all. Sometimes it might work, but the routing might be tens of miles away from the point which actually was set. Does anyone else have same problems (or fixes to it)?

I have a mark 4 navi + v27 os + 2006-2 DVD (Europe).
