I have a Garmin ETrex Vista. It comes with a serial cable to download information to a PC or grab the NMEA data stream. All you need for the RC is a null modem adapter and you're good to go.

Kevin's serial port library would make it pretty straight-forward to read and parse the stream. There is sample code for the BASIC Stamp, google can probably find it.

What is the RC your talking about? Is it the FIRST Robot Controller?
And Kevins code is written specifically for the PIC in the Robot Controller.....it would be of very little use to me.

You only said "microcontroller", not a specific target platform. I assumed you were using either the IFI Robot Controller or some variation thereof. It doesn't matter as long as it has a UART to read the data stream and parse it. You can use a BASIC stamp.
