The NP401's 12 million points of interest help you find nearby gas stations, hotels, restaurants, and other attractions when you're in unfamiliar territory. You can dial in a 3D view to help you navigate city streets or changes in elevation. Use the split-screen view when you need to see a closeup view of an upcoming intersection while still tracking your progress on a larger map. The system's text-to-speech function announces street names as you go, so you'll always know you're making the correct turn. The NP401 system works with Clarion's VZ401 and VX401 receivers.

Navigation Functions


Overview: The Clarion NP401 Hide-Away Navigation system provides turn-by-turn visual and voice assistance to direct you to selected destinations (when used in conjunction with a compatible Clarion in-dash head unit). The software quickly calculates step-by-stop directions to any destination available on the included navigation map. The navigation software uses Global Positioning System (GPS) satellites, and a digital roadway map database to calculate and display travel directions. The system's GPS antenna receives signals from a constellation of 24 satellites orbiting the earth and uses the strongest of signals, to determine your position to within meters.

Note: The NP401 is not a stand-alone navigation unit and requires a compatible Clarion multimedia head unit with monitor.

hHead Unit Compatibility: The Clarion NP401 Hide-Away Navigation system is an add-on navigation system for the Clarion VZ401 and VX401 in-dash multimedia head units. The NP401 connects to the Clarion VZ401 or VX401 using a single proprietary 10' cable (included).

OSD with Touchscreen Operation: The Clarion NP401 offers on-screen display and touchscreen operation via the Clarion VZ401 or VX401 LCD touchscreen monitor. Smart touchscreen controls enable you to access information at the touch of a fingertip. Layouts are designed to enable instantaneous display of desired information, while detailed information can easily be called up with a light touch.

GPS Receiver

SiRF GPS 20-Channel Receiver: The Clarion NP401 navigation system utilizes a SiRF GPS module with 20-channel GPS receiver to assure fast acquisition and accurate tracking of your vehicle's current location.

GPS Antenna: The Clarion NP401 includes an external GPS antenna with a magnetic base designed to mount outside of your vehicle. The GPS antenna features an attached 16' antenna cable which plugs into the SMB port of the NP401.

Note: The GPS antenna measures 1.5" wide x 0.6875" tall x 1.9375" deep.

Vehicle Positioning: The navigation software's computer considers vehicle speed and heading changes, together with longitude and latitude information, to accurately determine vehicle heading and position on a digital map. Signals from GPS satellites are used to determine the vehicle location. Three (good) or four (best) satellites must be received to accurately determine location. The GPS reception status is indicated by the GPS symbol on the map.

Map Data

4GB microSD-Card: All navigation data is stored on the NP401's inserted 4GB microSD-card. No disc drives or pickups are involved, so access to data is instantaneous. Maps are therefore rendered faster and scrolling is smoother. The absence of mechanical moving parts also provides higher resistance to shocks and vibrations for increased ruggedness.

Note: If you remove the microSD-card, you will lose navigation software and maps.

U.S. and Canada Map Coverage (by Tele Atlas): The NP401's 4GB microSD-card contains Tele Atlas map data for all 50 of the United States, including Alaska and Hawaii; as well as Puerto Rico, the Virgin Islands, and Canada.

Note: The map database used by the navigation software was created using high-resolution aerial and land based data collection. Car navigation maps are frequently updated. While the database was judged to be as accurate as possible at the time of its release, a map database an never be 100% accurate. Road information that is maintained in the map databases, such as turn restrictions or road names my change over time.

12 Million POIs Preloaded: The Clarion NP401 will guide you to your desired destination by accessing its 12 million Points Of Interest (POI) database. You can choose from National Parks, Gas Stations, Restaurants, etc as your destination and the NP401 will create and display your route in precise detail on your Clarion VZ401 or VX401 LCD monitor.

Map Updates: Navigation map updates can be imported into the system through the USB (type-A) port or via an external microSD card (sold separately).

Note: Music and other files stored on a USB memory device or microSD card cannot be played back.
