BRAND: Socket
MODEL: Cordless GPS Receiver (8550-00004E) BT
TYPE: NMEA-0183 (v2.30)
Works ?: somewhat (using rfcomm)
Startup Time (avg): 1m
Personal Rating: 6/10
Other Comments: Works great using gpsd and GpsDrive, but Maemo Mapper cannot reliably establish connection. Looking forward to Maemo Mapper version with gpsd support.

UPDATE: Was able to get connection to GPS by doing:
rfcomm connect /dev/ttyS3 00:0E:6D:6B:37:6F 1
in xterm; which resulted in:
Connected /dev/rfcomm0 to 00:0E:6D:6B:37:6F on channel 1
Press CTRL-C for hangup

then entered /dev/rfcomm0 into Maemo Mapper -Thanks Gnuite!

Unfortunately it doesn't work as well as gpsdrive. I often have to quit and relaunch a few times before it starts to work. Also, In my hilly area, I lose fix for a ffew minutes sometimes. When this happens, I have to go through the whole process again. GpsDrive manages to keep running smoothly using gpsd.
