Hi i just got the D3 installed i am having a bit of trouble with the D3 with the arrow ( showing current location )it is going sideways and not pointing to the direction i am heading... Any ideas? I just did a factory reset but that was only for the settings..

There should be an option to edit current location. Once you get there, you can manually turn the arrow to point it in the direction that you're facing.

I had the same problem and fixed it today. Push menu button then settings then hardware info, then 3D calibration. Click on each item on left and press clear for each of them. This should fix it.
