Garmin nuvi Navigators
When it comes to car GPS navigation devices, there are not many brands to choose from; but once you set your eyes on a specific brand, you still have a handful of models to choose from. Some come in budget flavors while others come with feature additives. Garmin is one particular heavyweight in GPS devices and their Garmin nuvi navigators deserve a closer look because their entry level models have plenty of things in common with their most expensive ones.
Design
Over the years, Garmin has been finding ways to slim down their Garmin nuvi devices while either retaining their hardware internals or improving them. Their upcoming 2012 models retain their curved rectangular shapes and sleek looks. Garmin also has a “prestige” lineup of ultra-thin GPS devices that resemble smartphones, making them highly portable. Many of their devices come in 4.3-inch and 5-inch flavors with both having the same resolution; so 5-inch displays are basically easier to see from afar.
Interface
The interface is what makes their Garmin nuvi devices shine because turning on the device for the first time reveals a very simple main screen consisting of two main icons along with some buttons on the bottom leading to settings and other features. The first icon serves as the quickest way to create a route where you are asked to state a definition and the device will calculate a proper route based on your current location.
The second icon takes you to the map so you can see your position and any surrounding points of interests. The map is colorful and detailed especially when you go to 3-D view where you can see some useful road sign icons along with streets and other possible routes. The interface is entirely touch driven and it is simple to zoom in and out of the map using one finger.
Common Features and Technologies
Just about every Garmin nuvi navigator should have the ability to plan multiple routes. This opens up a lot of possibilities because of the fact that it has over 6 million points of interest scattered in North America. Some devices may have Europe and Mexico maps as well. The text-to-speech engine adds convenience to the navigation experience so you won’t have to pay attention to the screen to make sure you are turning on the right intersection.
These devices also make use of a technology called HotFix satellite prediction which increases the speed of calculating your position for better accuracy. It works by predicting the movement of the satellite so it can come up with its own calculations based on its predicted course. Newer 2010 models include a nice extra called ecoRoute which takes fuel efficiency into consideration when calculating a trip.
Midrange and higher-end devices have a nice extra that can help people on the highway. This is called lane assist and it works by notifying drivers in advance which lane to be on before a critical exit turn needs to be made. Higher-end devices have Bluetooth connectivity to phones for hands free operation. Some models have variations where unlimited maps updates and/or traffic updated are included to vastly increase the lifespan of the device so the maps stay up to date and traffic data is properly shown so it can calculate better routes. These models have a letter suffix which means that the corresponding feature is free and it lasts a lifetime.
