Gps repeater do they make a repeater compatable with the gp31

I have posted the Operator Manual at
http://www.offscotland.plus.com/Temp/GP30-GP35-Operator's_Manual.pdf

Use this to check out section 7-10 to make up a cable to connect to a PC to allow download of data. Then, using the manual as a reference figure out the sequence of buttons to press to get the GP31 to download the waypoint and route data to the PC. Just press the buttons and assume the display is showing the next prompt. If you know someone you has a working GP31 get them to do the sequence and write down the buttons they press. You just copy the same sequence. You will need some software on the PC to capture the data,

Is this a request for a GP31 Manual? I have posted
http://www.offscotland.plus.com/Temp/GP30-GP35-Operator's_Manual.pdf which is basically the same beast.

If the Furuno unit you're referring to uses a GPS antenna with a coax (i.e. GP31/32) then the Tram antenna will work but the connector is wrong. The Tram antennas usually come with BNC connector and Furuno uses a TNC. Will need an adapter.

Make sure you installed the driver for the serial to USB adaptor cable.

Go to www.furunousa.com and download the installation manual

Hello!
Yes, the GP31 can connect to a PC.  With the wiring harness, it has an RS-232 port, which allows it to connect to most PCs, laptops, and even most palmtop systems.
Hope this helps you out,
Ken
