In revision 2091 we added a cumulative displacement filter, which should filter these updates out. Could you please update to at least 2091 and tell us if the problem persists? Thanks.

Since we didn't get a response here, and other users confirmed it works, I assume this is fixed with revision 2091.

I still experienced this bug on an n810. I have added a patch to use the direction from the cdf to redisplay the map. The compass still jumps all over the place when sitting still.

This bug is still present for the n810 as of svn2310, at least in the case of weak GPS signals. The map does not rotate as long as the speed is 0km. However when the GPS readings are weak the position data might jump around from place to place causing Navit to start redrawing the map.

Fixed in r3445
The r3445 added ability to specify per-vehicleprofile speed/distance thresholds for static position detection.
In addition, it should be updated again when the last shown position and the last reported position differ to much
