    Drift and Set Not Calculating in 12.7.16 (Navionics)

    I can't work out why drift and set is not being calculated after selecting "Calculate Set and Drift" in the System options in All Settings.  I believe I have all the NMEA sentences needed to do the calculation:

    $--VHW Water speed and heading
    $--HDT Heading true
    $--HDG Heading magnetic + deviation/variation
    $--RMC GPS position, COG, SOG
    $--VTG COG and SOG

    I also don't see TWA, TWS or TWD values unless I select to calculate them.  I know I'm receiving the NMEA sentences $--MWV and $--MWD

    What am I missing?
    I'm running v12.7.15 for Navionics.
