I have a few suggestions for the factory Garmin Nav unit in the new Wings ( who doesn't ? ). I would like to know if anyone has ever contacted them and offered info like this? I would think they would like to hear from the consumers about what would help sell their products. One of my suggestions would be to have input voltage readout on the screen to act as the much desired digital voltmeter that some Wing owners install. I have a GPS in my aircraft that does this so why not on the bike?
