RS232 LCD Display on NMEA

[lockie]

I'd like to have a small display in my cabin to allow me to read lat/long, speed, depth etc from my cockpit-mounted NMEA instruments (Navman log and Raymarine Bidata).

I can shell out many bucks for a proprietary display, but I thought it would be an interesting project to buy a generic RS232 multiline display and connect it via an NMEA/RS232 converter, and configure it myself.

In theory it doesn't sound too hard, has anyone done this?
