Where did you hear that 2.0.1 had anything to do with updated gps routines? Everything I’ve read said that won’t be touched until the 2.1 firmware. The updated routines to pull speed and direction are in the 2.1 sdk.
Generally with any software you wouldn’t get a major new feature like turn by turn with such a minor revision number change (ie 2.0 to 2.0.1). The 2.0.1 designation implies it’s nothing more than bugfixes.
