I have been told by flight attendants to turn my GPSr off, which of course you need to comply with. While the chance of interference is fairly low, GPS receivers employ local oscillators that do emit RF into the environment, just like any radio receiver. It is possible (though quite unlikely) that these signals could interfere with aircraft navigation, so naturally airlines are paranoid about this. Otherwise, carrying a GPSr onto a flight is almost never a problem as long as it is off.

i use a sony clie (palmos 5) with my mac. admittedly, i use GSAK and garmin mapsource within VirtualPC to do a lot of the work, but that's just out of frustration with the equivalent (or non-existant) analogs on the mac side.

I recently found a cache in Maryland "Covered Bridges #3 (Loy's Station Bridge)", and found that the log was littered with notes from letterboxers that were less than kind. They refered to geocaching as "Geotrashing" and suggested that geocachers "find a real sport". What gives? It turns out there is a letterbox very close by to this one, and I guess some letterboxers found the cache by accident. Is this common, or did these letterboxers just have a bad day? Does this upset anyone as much as it did me?

After posting that, I went and did some testing, and it seems to also work perfectly fine if you Enable USB in VPC, install the drivers in XP, then plug the usb adapter in. An XP reboot after installing the drivers and before plugging the device in may be necessary, refer to the instructions that came with your particular adapter. Using this method, my GPS showed up on COM3. hope this helps.

It is most likely possible to get it to work. I have a eTrex Legend and the IOGear usb/serial adapter, but both use the same MapSource software and the serial adapters probably use the same chip. What I did is disable USB support in the PC settings in VPC, and make sure you have the usb/serial adapter drivers installed in OS X. Then plug the USB/serial adapter into the computer. Then, set COM1 in the PC settings in VPC to usbserial0 (this is what my adapter shows up as in the menu, yours may vary). You may need to fiddle with the flow control setting checkboxes. Sometimes it helps to reboot windows after changing the VPC settings. It takes some tweaking, and will sometimes not work, but I have managed to upload map data and waypoints and download tracks from the GPS successfully, as well as use the gps in NMEA mode with Streets & Trips within VPC and with Route 66, Terrabrowser and MacGPSBabel for OS X. If this doesn't help, let me know and i'll be glad to help you troubleshoot.
