The whole idea is, I have several GPS units with no display and I wanted an easy way to see my position. I have the option with the HamHUD II to see this, but it uses up precious display space that I rather use to display some APRS related information instead. So, I need a way to take the NMEA data comming out and display it in a simple format that can be read easily while driving down the road. Link.
