The Garmin nüvi is a line of portable, dedicated personal travel assistant and GPS navigation devices introduced by Garmin in 2005
Dedicated Navigation: It operates independently of cellular networks, relying instead on built-in satellite receivers to provide uninterrupted offline positioning and route calculation
Form Factor: Devices feature color touchscreen displays typically ranging from 3.5 inches up to 7 inches diagonally, designed to be pocketable or mounted easily onto a vehicle dashboard or windshield.
Turn-by-Turn Guidance: It delivers spoken text-to-speech directions that announce explicit street and highway names rather than just generic prompts.
Preloaded Mapping: Ships with regional or national street maps and extensive points of interest (POIs) such as gas stations, restaurants, and hotel
