About the Centennial SatNav GPS Card driver...
            ==============================================

1.  This driver works only with 2.x Newton devices and has only been
    tested with MP2000

2.  This driver supports only the binary protocol version of the 
    SatNav card. The NMEA version will be supported by GPS Map 2.0.
    If you have already a NMEA version you may get a 2.0 beta version.

3.  The driver runs only with GPS Map 1.8.5, GPS Map Lite  1.2.5 or later.

4.  The driver installs as a system extension. You must start it
    by tapping onto its icon for changing the settings. If you are using
    a GPS Map (Lite) 2.0 beta you may also select and setup the driver
    through the GPS Map preferences window (Interface settings).

4.1 Select the hardware interface you want to use. The serial option
    may be of interest for connecting to an external Rockwell receiver.

4.2 Select the desired update rate. One update per second is fine
    but needs 2 watts of Newton's batteries. One update per five
    seconds my be enough and reduces the power consumption to around
    0.75 watts.

4.3 As the receiver itself has no battery buffered realtime clock it
    must be initialised with the Universal Time (UTC) by the host
    computer, otherwise it will need up to 15 minutes for getting
    the first fix. UTC is the time at zero longitude. The driver uses
    Newton's system time, the offset time at your location as set
    within the "Time Zones" application and the summertime setting
    for that location for automatically calculating UTC. You may
    check the calculated offset and in unusual cases you may need
    to correct it.
