Tripy II for moving map in Oziexplorer

I cannot seem to get my Garmins to work (USB) as the GPS for moving map function and was wondering if any one has or knows if you could use the Tripy II as the GPS for this function?

If anyone could also help with getting the Garmins to work that would be great. I follow all the right steps and it says that it has found the Garmin USB device the boxes are ticked but when you Start the moving map it just comms up saying there is a comms error with the GPS.

I can't seem to get around this despite trying all sorts of combinations.

Very frustrated and would love to have the feature working.
Cheers
Kelvin
