Dash gauge is smartphone based. You can even add a card and activate and use as your phone. Assume it will have GPS, gyro etc. built in like all smartphones. Varg has said their will be all manner of ride statistics available including "air time", so probably some other neat stuff. We don't yet know if one can use/run other apps while phone is clicked into cradle or if doing so locks out all other apps while its running in "dash gauge mode".
