Five Tips for buying a car navigation instrument
Buying matters 1: screen size
When selecting the GPS navigator, the first thing you want to see is the size of the screen.The current most styles have reached 4.3 inches, but if you can accept a smaller display, the price will be more beautiful.For example, the market price of 3.5 -inch powerful Garminnnüvi265T has been reduced from $ 330 to only $ 135, and the 4.3 -inch style of the same manufacturer still costs $ 172. It seems that the small -size style is currently more cost -effective.
However, there is also a disadvantage of small size, that is, it is not suitable for people who cant look at small characters in poor eyes.If you have serious old flowers, choose Magellanroidmate1700.It has a 7 -inch extra size, and the 800X480 resolution WVGA display can also ensure that you dont need to squint your eyes to see the street name.Just remember that the larger the screen, it means that it will occupy more space on the dashboard or in front of the windshield.Compared with the balance, the 5-inch Tomtomxxl540-S is a good choice after compromise. On the one hand, it has a thin and light body, and on the other hand, the screen is enough to see the map and ensure that the touch input will not be wrong when the touch input will not be wrong.The price has also dropped from $ 300 to about $ 168, which is worth buying for most consumers.
Buying matters 2. Randomly attached maps and interest points
In terms of maps, almost all GPSs are preset in the US map, and some styles will be added with Canadian, Mexico, or Puerto Rico.If you need other maps, you can buy it by the product manufacturer, or load the SD card through your computer.
Since road construction and building demolition are inevitable, maintaining the latest map is also crucial for GPS.In this regard, large navigator manufacturers have great advantages. The reason is that both Tomtom and Garmin have provided free or single -time paid maps.On the other hand, most other manufacturers will charge fees for each update map, and Magellan even updates the asking price up to $ 150, so you must check the map update policy when buying.
The same important delivery service as the map is the integrated interest point (POI) database.For example, you can find the nearest Chinese restaurants, HOMEDEPOT, car repair shops, or tourist destinations through this service.The size of the POI database provided by each manufacturer is very different, and the performance of each product is different in processing the search results.Tomtom and Garmins various products have intuitive, extremely correct interesting points search results, and some can even integrate mobile phones to perform various types of online interest points search; the database provided by rotten navigators may allow you to break your head and find it and find it.No gas stations showed by the search results.The most secure method is to read the product evaluation before buying, and pay attention to the performance of the POI.
Precautions III, real -time road conditions and data services
The best part of the navigation instrument is not only to make you no longer get lost, but also find nearby gas stations and attractions through interest.Excellent products can also help you avoid the most annoying situation of driving: traffic blockage.In order to prevent traffic jamming, you need LiveTraffic real -time road conditions update function.
There are several ways to get real -time road conditions.In terms of navigator, the "T" of Garminnüvi265T is the road conditions service. It will let you know whether you will get a traffic jam on the road and provide a new alternative route.265T also provides free real -time road conditions. Unlike Tomtomgo740live, you need to pay $ in October to share the service on the real -time map, but there is an advertisement jumping out when opening the traffic information.For navigators such as Tomtomone140-S without built-in road conditions, you need to buy additional receiving equipment.However, this method will increase the weight of the navigator, and it is equivalent to letting multiple cable dangle in front of your windshield, so it is best to choose a built -in style.
Another new way to get real -time road conditions appeared last year.To put it simply, it is a wireless electric connection service to receive road conditions update, and network functional services such as Internet interest points can be used.For example, Insignians-CNV43 navigator integrates the built-in connecting Google search function, and has Twitter capabilities to share the journey immediately.When you have the ability to connect the network, you no longer have to worry about your interest will be outdated; however, the cost is to pay additional connection service costs each year (insignia costs $ 99 per year).The machine is the navigator.
Buying matters 4: voice control and other additional functions
There are many GPSs on the market that can be controlled by voice, allowing users to put both hands on the car steering wheel without touching screen operations.At present, the best GPS of voice control is Garminnüvi885T.The navigator with a market price of about $ 280 can be combined with wireless links with the steering wheel. Opening the voice control mode can perform a variety of functional control, which truly exerts the entire potential of sound recognition.In the "PCMAGAZINE" test, 885T can accurately execute the voice command. In contrast, the range of voice recognition function of Magellanmaestro4700 is very limited and cannot operate accurately.
If you want to watch entertainment content such as movies on the navigator, many products support audio and photos, or you can play video images from SD cards.These functions may not be particularly important, but it is recommended to integrate the mobile phone usage interface here. This means that GPS can connect to the mobile phone through Bluetooth function and directly access the list of liaison people. With voice functions, users can also use voice to make calls, even Bluetooth Bluetooth, even BluetoothYou dont need to wear headphones, and high practicality.At present, only the high -priced GPS on the market has a combination of mobile phone equipment. If you are particularly dedicated, please remember to check the use of telephones to the navigator manufacturer before purchasing.
Buying matters 5: Whether the smart machine is better
Finally, what you need to consider is whether the smart machine is more suitable for you.Last year, Apple and Googles Android Software Stores launch a bunch of new navigation applications, which is equivalent to turning iPhone and Google smart machines directly into GPS navigators.In particular, the latest operation procedures of Android and GoogleMaps prompted by voice intersection are characterized by the characteristics of Googles interest point search service, which looks more outstanding than ordinary navigators.Its small disadvantage is probably the need to buy an additional mobile phone stand on the windshield, and the navigation function will also make the smart machine out of power quickly, and consumers must think twice.
