regibeau, I have a Magellan Meridian Gold. I like it very much. On my "want" list is the compass of the Meridian Platinum, but that was just a few $$ too much. It works well for me. For driving I throw it in the windshield area, connect to the Ax and use Mapopolis for directions. I prefer this to a CF card GPS because I can take the Meridian out in the weather and not worry about it. IF I used a CF card, I think I would go with Holux. Low power consumption and fast locks.
Dave, I think I posted that somewhere
here. The only difference I would make to the suggested steps is that I would start Mapopolis before connecting the cable. Activsync looks at the serial port, and if any data appears, it kicks in and tries to sync. That locks up the com port. So, start your mapping software first, let it lock up the port, then connect the serial cable with the GPS running.
If your software doesn't start the com port, use Holux' GPSViewer to initiate the communications with the GPS, then shut it down and start your nav software.
If that doesn't work, PM me and we can talk offline.
