Bearing on map ok, wrong on compass
do I make an error?
My setting is only GPS compass, as the device doesn't have on. My map is set not to rotate, so my position arrow shows in the direction I'm driving (Map top is north).
On the map my direction is displayed correct. When I'm driving west, the arrow shows to the left side. That has always worded correct.
Now I checked the compass while approaching a waypoint. The compass almost always showed that I'm driving more or less East (around 90 degrees) while I was driving West. The arrow in the compass pointing to my destination (waypoint) was set to the correct degree, but pointed in the wrong direction (as the compass was wrong, as well).
Then I drove a 270 degree turn, the compass turned slowly almost to N (0 degree) but fall back to East again, after my turn changed into an straight street, again( heading north).
Am I'm doing something wrong?
That happens with the internal GPS sensor and an external Bluetooth one (Navilock BT 821G).
