When new roads are opened or buildings are changed, the difference between the navigation map and the actual situation can be confusing.

Recent genuine car navigation systems work in conjunction with the back camera and various in-vehicle sensors, and incorporate functions such as managing and controlling the state of the vehicle, making it difficult to easily replace it with an external product like in the past. situation.

In addition, the fact that the car ownership period is getting longer is one of the reasons why people continue to use old map data.

How can I update outdated map data?

Recently, it is said that map data can be updated in various ways. rice field.

"The quickest thing is to ask the dealer to update the car navigation system. Although it costs money, there is a sense of security that problems are less likely to occur because it is an update of compatible official data."

Although there are differences depending on the manufacturer, it is said that genuine navigation data is updated about once a year.

In order to link this update frequency, some manufacturers have prepared a service that allows you to receive free map data updates up to 3 times in 3 years from the purchase of a new car.

How much does it cost to update the map data at the dealer?

"The update fee for the car navigation system is about 15,000 yen to 25,000 yen plus the update data fee. The labor fee varies depending on the store, but it costs 7,000 yen for things such as attaching and detaching the HDD navigation system. There are also manufacturers that charge for front and rear labor.Please contact the dealer directly to confirm this.” (Mr. N, owner of a used car dealership)

The cost of 20,000 yen to 40,000 yen to update the map data of the car navigation system seems expensive.

However, we recommend that you do not give up and look up the model number of your car navigation system. This is because some car navigation systems can be upgraded for free depending on the model number.

For example, with Nissan's "holiday spot update compatible" navigation system, you can update the data simply by removing the SD card from the main unit, downloading new data to the SD card via the PC from the dedicated site, and inserting the SD card into the car navigation system. I can.

Also, imported car manufacturers such as BMW and Audi are developing a service that allows you to upgrade yourself. In this case, you need to register on a dedicated site, or you need a separate dedicated data plug, so the hurdles seem a little high, but you don't have to pay labor.

"Another method is to buy a second-hand media that contains new map data and update it yourself. It's uncertain if you can get the latest version, but at least it's nearly 10 years old. The car navigation system installed in the car does not support the connected services that each manufacturer has recently developed.

It is cheaper to obtain and update new map data on SD or DVD by yourself. Unlike a dealer, you will be responsible for your own responsibility, but if you have the skills to update the OS of a computer, you should be fine.” (Mr. N, owner of a used car dealership)

Car navigation systems are categorized into "genuine car navigation systems" that are installed in new cars and "external car navigation systems" that are installed after the car is purchased.

First of all, the genuine car navigation system is characterized by being fitted perfectly on the dashboard. This genuine car navigation system also has a difference between "dealer option" and "manufacturer option".

The car navigation system, which is a manufacturer's option, is installed on the car's production line. It is characterized by total control, such as matching with the instrument panel design and interlocking with various sensors.

Dealer options are, as the name suggests, installed at the dealer. Although there are size restrictions, there is a possibility that you can choose products relatively freely.

Both display accurate location information in conjunction with GPS, G sensor, vehicle speed sensor, etc., but on the other hand, it is difficult to replace easily, and there are restrictions on operation and functions (such as while driving). It is said that there are many things that are affected.

On the other hand, in the case of external car navigation systems, high performance with enhanced operability and entertainment is attractive. It is also a big point that you can choose various models and monitor sizes according to your budget.

There is also a navigation that can update map data using cloud data, and there is also an advantage that it is easy to use new map data.

As a demerit, if there is a failure or defect, it is necessary to communicate with the audio manufacturer or the store where you purchased it, and it is annoying that there are many cases where the warranty period is short.

As a recent trend, the installation rate of genuine navigation systems that are cheaper to install than before and are linked with sensors, back cameras, and advanced driver assistance systems is increasing, and this is one of the reasons why old map data continues to be used. It is also

Until now, most car navigation systems were in-dash types that fit neatly inside the dashboard, but recently, on-dash types have increased as navigation screens have become larger.

However, most genuine on-dash car navigation systems have a fixed monitor, and it is difficult to replace the monitor like an in-dash type.
