Does anyone know if it is possible to "feed" GPS coordinates into Maemo Mapper? What I am thinking is the following: I have an old (but perfectly adequate) Garmin eTrex GPS, which has serial output. I could hook that up to a cheap old USB-to-serial adapter (* I am assuming such an adapter would work) and then poll the GPS and feed the coordinates to MM every couple of seconds or so.
Any ideas?

Such an adapter wouldn't work as usb host mode isn't enabled on the device.

In the Settings dialog, there is a field to specify the "MAC Address" of your bluetooth-enabled GPS receiver. If that field starts with a "/" character, then it is actually interpreted as a regular file in the file system, meaning that Maemo Mapper will simply read NMEA data straight from that file. This allows it to work with RFCOMM, but it also means that you can use mkfifo and send NMEA data from just about anywhere into that file.

As mentioned before, though, the bigger problem is getting your serial-to-USB adapter to work...
