My Garmin Zumo 550 at night. Its been very helpful traveling with this GPS. The Zumo was designed specifically for the motorcyclist. Its waterproof, vibration proof, has a big bright screen and touch screen controls that can be activated with gloved fingers. It has many features such as a fuel calculator, compass, elevation, trip data etc. Its also an mp3 player and I can hook up a mobile phone thru the unit and rout it to helmet speakers via bluetooth.
