Even though smartphone navigation apps have become almost ubiquitous, automakers are offering more in-dash navigation systems in vehicles than ever before. If you’re thinking of including an in-dash “Nav” in your next vehicle, heres some things to know.
Screen Size
One of the most important aspects of choosing an in-dash Nav system is screen size. Screen size can range from 5 inches to 10 inches. Regardless of size, make sure that the screen is easy to see, even in bright sunlight. If the display is a touch screen, ensure that it’s simple to use.
Many Nav systems allow you to input destinations using voice activation but voice input doesn’t always work well. This is definitely a feature you need to try before you buy if you intend to use it extensively.
Mapping Software
A Nav system is usually only as good as its mapping software. One of the most important aspects to consider is where the map data resides. Many systems store map data on a DVD or HDD. But roads change constantly, so these need to be updated often. The latest way to store map data is on an SD card, such as in Ford’s MyFord Touch system.
Map graphics are another key feature. Some systems provide a more realistic map view than others. More advanced navigation systems have enhanced graphics, including a 3-D mode. Others have icons for individual points of interest (POIs) or even branded POIs that show where the nearest Starbucks is located.
Destination Input and POI Data
Most Nav systems provide various ways to serve up a route to a destination: by an address, an intersection, a POI, a point on the map, or even a phone number. Many systems include an address book and allow users to set a “home” destination for quick routing. Some will locate and route you to emergency services such as police and hospitals in the area.
Routing Quality
Many systems give you a choice between different routes, such as the shortest or quickest. Others will let you tailor a route to avoid toll roads or freeways. Many systems offer a split-screen mode when approaching a turn. It shows the route map on one side and the next maneuver on the other. Some even provide “lane guidance” to show you the precise lane in which you need to be. This can be particularly helpful when you’re negotiating a complex freeway interchange..
Other Features
Beyond these basics, many Nav systems provide various convenience features. A common one is “geo-fencing” that allows you to set up areas to avoid. Many systems also now include some form of traffic information, although many such services are subscription based. These systems usually use color-coding and symbols to indicate traffic flow. Some systems will also actively warn you of traffic along a chosen route in addition.
Nav systems in some SUVs or trucks have off-road routing capability that lets you set GPS waypoints so that you can find your way even where there are no roads and signs. And many systems include a “breadcrumbing” feature that marks where you’ve been on the screen in case you want to retrace your steps.
