I was wondering if anyone knows of any good gps/ff/sonar units that would allow me to view my motor readings (speed, fuel comsumption, oil/water temp, etc.) on the unit instead of having to drill holes into the console for separate gauges. Is this even possible? I think it would be a really clean setup having everything on one digital display if possible. It would be used on a yamaha f60 or 70 if that matters. Recommendations and suggestions are welcome.
