Currently running an ASUS A636N PDA/GPS with OziExplorer. Can access all maps ok, but when I try to run moving maps, it gives the message 'No data received from the GPS' Any ideas on why?

You can use Hyperterminal (which is included in Windows) to see if data is comin in from the GPS. Don't forget that unless your GPS is receiving satellite data non will be shown so (and I'm not trying to be patronising here) make sure the GPS is outside.
Set Hyperterminal to the baud rate that your GPS says it is working at. Select the comms port that the GPS is working through set the other bumph to none,8,1 and then watch the screen.
If you are getting lines of GPS "sentences" (NMEA data) then the GPS is OK. From there it is simply a matter of checking that the GPS settings in OziExplorer match those you set to make Hyperterminal work. (Don't forget to stop Hyperterminal before trying OziExplorer.)
4800 Baud is fast enough for most purposes so see if you can set the GPS and OziExplorer to it.
Click Start NMEA communications with GPS (under the Moving Map menu).
Under Moving Map you can also click "Show NMEA input and output" and you should see the same sentences as you did in Hyperterminal. If so, Moving Map should work.

Oops, you might not have hyperterminal in your PDA, but you should still be able to use the "show NMEA input and output" to see if the comms are working.
