What brand and model of bluetooth GPS are you using?

Does it work (with the built-in map) when you configure it using the location control panel applet for the GPS.

The port is 2947, not 2937 for the gps port.

The GPS has to send out GPRMC or GPGLL sentences (correctly) for me to get a lock. It is possible the GPS is in some other mode.

It should be creating a minigpsd directory with subdirectories. Find the largest ...prelock.zip file and send it to me via PM or otherwise attach it.
