Seeking a great navigation value? Look no further
Sometimes one forgets that having a computer in the form of a smartphone makes things a lot easier than they were even ten or fifteen years ago. GPS guidance is one of those areas where phones have been a real help, but one can't always rely on cell service to make sure the phone's delivering the right directions. For those wanting an inexpensive in-dash solution, the DM620N navigation receiver from Dual delivers reliable maps on a spacious 7" touchscreen display. It also boasts a dedicated smart assistant button and much more for entertainment on the go.
Get where you need to go
The Dual DM620N boasts maps of the entire U.S., Puerto Rico, and the U.S. Virgin Islands, with an extensive database of 1.2 million points of interest. You'll see the maps laid out clearly on the receiver's easy-to-follow 7" touchscreen, while the intuitive user interface makes finding your way a piece of cake. iGO primo navigation software ensures you're getting the most reliable routes, while lane guidance keeps you on the right path for your next maneuver. In some instances, you'll see realistic depictions of complicated intersections or 3D representations of buildings and landmarks to help orient yourself. When you're ready for a map update, the front-panel SD map card slot makes it easy to get current.
Shallow chassis and a sweet 7" screen
Dual lets you put this multimedia marvel in more dashes with its shallow chassis, so it'll fit in a wide variety of double-DIN openings. The 7" display delivers a clear picture of maps and album artwork. And Dual still found a way to make room on the bezel for a USB input, aux input, and a smart assistant button!
Access your phone's smart assistant in a jiffy
Dual recognizes that our phones are not getting any less important to our day-to-day activities, so they designed the DM620N digital multimedia receiver with a dedicated push-to-talk button for your smart voice assistant. Whether you use Siri® from Apple or Google Assistant™, you'll be able to summon your assistant quickly by pushing the convenient button on the stereo's bezel.
Talk hands-free with built-in Bluetooth®
Built-in Bluetooth connectivity lets you make and take calls with your compatible phone through the DM620N. This Dual gives you full access to your phonebook, so you can keep your phone safely stowed away, and a built-in microphone means less time running wire during your installation.
Wireless music streaming
Built-in A2DP technology allows you to stream your tunes from your smartphone through this receiver, so you can access all the music on your Android phone or iPhone®, whether it's stored music files or streaming services. And the Dual iPlug Smart Remote smartphone app lets you turn your phone into a remote control so your passengers can command the action from anywhere in the vehicle.
Play your favorite tunes
This receiver offers a front aux input connection for more audio sources. Load up your thumb drive with tunes for your travels (including lossless FLAC files) — the receiver's front USB port provides convenient access, not to mention plenty of charging power for your devices. You can also connect a rear-view camera, so you can see more of what's behind your vehicle when getting in and out of tight spots.

7" LCD Touchscreen Monitor: The Dual DM620N features a 7" touchscreen LCD monitor with LED backlit. The screen has a resolution of 800 x 480 with 1,1520,000 total pixels. This unit has touchscreen controls with interactive icons and graphics, making menu navigation easy.
- Hard-Keys: There is also a 3-way rotary knob and three push-buttons along the left edge of the screen for the most frequently used functions; including Volume/Mute, Push-To-Talk, Navigation Map, and Previous/Next Track.
- Key Beep: The in-dash head unit provides an audible beep to confirm button operation (this can be turned On or Off).
Push-To-Talk Voice Assistant: When connected via Bluetooth to an iPhone with Siri or Android smartphone with Google Assistant, you can access the mobile device's digital voice assistant through the Dual receiver by pressing the "Push-to-Talk" button on the front-panel. You'll speak your command into the head unit's front-panel microphone and the digital voice assistant will be heard through your vehicle's speakers (music playback will be attenuated). Compatible digital voice assistant functions include hands-free calling, music search, setting reminders, text-messaging, audible navigation, and more. You'll be able to ask your digital voice assistant get directions to a destination and the turn-by-turn instructions will heard through your vehicle's speakers, while the on-screen map still displays on your compatible smartphone. The head unit's audio is attenuated while the digital voice assistant provides voice prompts.
Note: The head unit's LCD touchscreen will only display hands-free calling and Bluetooth audio information (all other digital voice assistant functions are only audible through the Dual head unit; visual data will still need to be viewed from your smartphone device).
Dual iPlug Smart Remote App: The free Dual iPlug app (for Apple iOS 9.1+ and Android OS 4.4+) turns your Bluetooth connected Apple iOS or Android OS device into a wireless remote control for the DM620N receiver.
- Head Unit Control: This app controls most of the primary functions of your receiver, including Power On/Off, Source Selection, AM/FM Tuning & Presets, Play/Pause & Previous/Next Track, as well as Volume, Mute, & EQ.
- NAV Button: Once the app is installed your smartphone and the DM620N is connected via Bluetooth, the "NAV" button on the receiver's touchscreen monitor allows you stream audio from your favorite navigation app on your connected phone through your car speaker system (visual navigation is still done from your smartphone and not the Dual receiver).
iGO Primo & TomTom Navigation: The Dual DM620N contains map coverage of the United States (all 50 states), Puerto Rico, and the Virgin Islands with over 1,200,000 points-of-interests from TomTom; all stored on the pre-installed 8GB microSD card (the microSD card must remain installed at all times). The map database was created using high-resolution aerial and land based data collection. The DM620N employs iGO Primo navigation software for turn-by-turn visual and voice assistance to your selected destination. The software quickly calculates step-by-step directions to any destination available on the included on-screen navigation map.
Note: While the receiver's map database was judged to be as accurate as possible at the time of its release (2019), a map database can never be 100% accurate. Road information that is maintained in the map databases, such as turn restrictions or road names may change over time.
Map Updates: iGO offers periodic updates (purchase fees will apply) for data such as roads, new addresses, and other navigational information that will keep the Dual navigation system up to date and provide the best possible experience. For updates and add-on options, please visit www.naviextras.com (requires Windows XP or newer; not compatible with Mac). A free program called "Toolbox" can be downloaded from this website so you can create a copy of your map as a backup, as well as assist in easily checking for updates and optional features that are available.
Note: You have 30 days from purchase to download the latest available map free of charge.
GPS Receiver & Antenna: The Dual DM620N features a built-in GPS receiver and includes an external GPS antenna which determines vehicle speed and heading changes, along with longitude and latitude information, to accurately determine vehicle heading and position on the system's digital map. The GPS antenna is designed to be mounted on top of your dash inside the vehicle or on the roof outside of the vehicle.
- Start-Up Time: The Dual DM620N takes approximately 10 seconds to go from "off" to the last source selected. The unit then takes approximately another 10 seconds to go from a source screen to the navigation map.
- Calculation Time: It took approximately 33 seconds to calculate directions from Charlottesville, Virginia to Los Angeles, California. It took approximately 17 seconds to calculate directions from Charlottesville, Virginia to Baltimore, Maryland. These tests were done inside the Crutchfield Lab of the Crutchfield Headquarters. Results will vary based your surrounding area and available GPS signal.
On-Screen Map: The unit's on-screen map shows your vehicle's current position (a blue arrow by default), the recommended route (an orange line), the surrounding map area, and your destination as a checkered flag. The on-screen map shows streets, roads, and highways in a way that is similar to how a paper road map shows them. A road's width and colors corresponds to their importance, so you can easily tell a freeway from a small street. When navigating a route, the top section of the map screen shows information about your next route maneuver and the next street or the next city/town. When approaching a turn, the map screen will zoom in and raise the view angle to let you easily recognize your maneuver at the next junction. If the next turn is at a distance, it will zoom out and lower the view angle to be flat so you can see the road in front of you. The map also displays data; such as the posted speed limit, your current speed, current time, distance to your destination, time left before you reach your destination, and your arrival time.
- 3D/2D Map View: Switch between a 3D or 2D map view. The 3D map view provides three-dimensional terrain (including hills & mountains), elevated roads (like overpasses or bridges), plus three-dimensional landmarks and buildings. Similar to paper road maps, the 2D mode, shows you streets, roads, and elevation by color.
- Color Mode: The navigation map screen uses different color themes (Day/Night) during the day and during the night for both the map and the menu screen. Daytime colors are similar to paper road maps, and the menus are bright. The night color themes use dark colors for large objects to keep the average brightness of the screen low. You can also set the navigation unit to switch between daytime and night color modes automatically based on the current time and GPS position.
Note: You can continue to listen to a selected source while viewing the on-screen navigation map.
Lane Information & Signposts: The Dual DM620N's navigation map offers helpful lane information and signpost guidance, along with junction & tunnel view, as well as tunnel view and freeway services.
- Lane Information: When navigation on multilane roads, it is important to take the appropriate lane in order to follow the recommended route. If lane information is available in the map data, the map screen will display the lanes and their directions using small arrows at the bottom of the map. High lighted arrows represent the lanes you need to take.
- Signposts: Where additional information is available, signposts substitute arrows. Signposts are displayed at the top of the map. The color and style of the signposts are similar to the real ones you can see above the road or by the roadside, They show the available destinations and the number of the road the lane leads to.
- Junction View: If you are approaching a freeway exit or a complex intersection and the needed information exists, the map is replaced with a 3D view of the junction. The lanes you need to take are displayed with arrows. Signposts can also be present, if information is available.
- Tunnel View: When entering a tunnel, the map is replaced with a generic tunnel image so that surface roads and buildings will not distract you.
- Freeway Services: When driving on a freeway, you have the navigation system check for the next exit with service stations, restaurants, or lodging.
Audible Alerts: The Dual DM620N offers various audible alerts and functions to help you get to your destination safely. It does not offer Text-to-Speech (only turn-by-turn instructions).
- Voice Guidance: In addition to graphic directions, the DM620N provides voice guidance with turn-by-turn instructions. You can select from English, French, Spanish, Italian, Korean, Japanese, and Chinese audible languages. The volume of the voice prompts can be increased with increases in speed to overcome road noise. Voice guidance can be turned off if you prefer.
- Safety Alert: This function can warn you when you approach road safety cameras, school zones, or railroad crossings (if available). You can also add your own alert points. Beeps or the spoken type of alert will be heard when you are approaching of these points.
- Speed Limit Warning: Some maps may contain information about the speed limits of certain road segments. The DM620N provides an audible warning if you exceed the recommended speed limit.
Note: While navigating, other sources may be selected and listened to; such as AM/FM Tuner, USB, & Bluetooth. The unit will mute the audio of the other source during navigation voice-prompts.
Destinations & Location: The Dual DM620N provides you with your location status, as well as offers you a variety of ways to search for a destination.
- Find Destination: From the "Find" menu, you can select your destination by entering an address or selecting a place of interest (1,200,000 POIs), a location on the map or one of your Favorite destinations. You can also look up your recent destinations from Smart History, enter a coordinate, or use the location saved in a photo. iGO primo offers you several ways of choosing your destination:
- Browse Map: Select a point on the map for your destination by touching the screen.
- Address: Enter a full address or a part of an address; for example a street name without a house number or the names of two intersecting streets. Or enter ZIP code only; this way you do not need to select the name of the city and the search for street names might be faster as well.
