Well I have partly solved it to get the direction indicator working.
With my phone not having the necessary hardware ie. a magnetron, I downloaded an app that is a compass that is derived from the GPS.
This works fine as long as I am moving, however when you stop say bye bye to the compass.
So my OS mapping works really good when I am on my bike, though not so good when I am walking, unless I walk reasonably fast.

[size=78%]In answer to the post by gunwharfman you cannot really blame the app at all, only the phone, for not having the necessary hardware namely the magnetic sensor. [/size][size=78%] [/size]
