Hooking up GPS

If you're trying to hook up your GPS unit (in my case, a Garmin eTrex) to your mac, it's worth it to (1) buy the Keyspan USA-19HS serial-usb adapter - it just *works* and (2) make sure your GPS is in Garmin (or appropriate) mode, and not just NMEA if the application you're using to communicate expects the Garmin Serial protocol. Yeah, that was about a day of 'debugging'. It was compounded by the fact that MacStumbler can accept the NMEA protocol, and so would actually mark the acceess points it found, and therefore I didn't think anything was wrong.

In the end, however, the connection works terrifically. GPSBabel works (both in GUI form and in command line form) as well as GPSConnect and Terrabrowser, both by Chimoosoft.

I want a decent Photo-GPS linking application. If only Terrabrowser was open-source I wouldn't be tempted to make my own solution from the ground up.
