Can i use this device in my new boat to monitor tach, speed, batteries (3) and gas level? maybe have 2 screens. the first one whould show tach, speed and fuel. the second one would show 3 batteries voltages? Although a little (o.k., a lot) more expensive, you could look into Chetcodigital for marin...

Just thought I'd suggest that you start a gallery for how people have their GX's in their PC's and any screen designs they might have.....unless you'd rather it just be included in the "general" Gallery.
