I never used this unit and is like new in excellent condition and never left the house. There are no scratches or scuffs on it because it is new. The box was opened, battery charged, and latest maps downloaded. Right now, I need the money more than this wonderful GPS navigator. The rugged 750i has the flexibility of on/off road navigation with global messaging and interactive SOS via inReach satellite technology plus a built-in 8-megapixel camera. This unit supports text messaging, posts to social media, or communicate via inReach device to inReach device in the field (active satellite subscription required). In case of emergency, trigger an interactive SOS message to GEOS, a professional 24/7 global monitoring and response center.
