I haven't found data on the rbt2300 yet but do you happen
to know the firmware rev on the unit.  If you have the
urge, you can pull it out of the nmea logs when the unit
starts.  Latest FW I've seen on sirf3 is 3.2.4 so am
curious as to whether the RBT units exceed that.

As an asside, it looks like there is now a sirfflash
utility out there which can flash sirf3 units including the
Holux gpslim236 to 3.2.4.  Could make for an interesting
experiment, wish I still had a sirf3 unit around.

A competent navigator is not the skipper who can press a button
and follow a       command, but one who uses all the tools at his
 disposal to navigate his course safely and efficiently.
