Nowadays, GPS no longer simply provides you with a fixed and static map of the road network.

They incorporate a multitude of important criteria to ensure a successful trip: speed limits, points of interest, dangers… This tool quickly loses its value if you do not have the latest updated version. You have understood how important it is to update your navigation assistant. But another question arises: how often should you install the new maps? The number of updates to be performed per year depends on your personal use.

Of course, if you only use your device once a year to go on holiday with your family, a single annual update will be more than enough. On the other hand, if you drive on a daily basis and have to go to unknown addresses on a regular basis, it may be a good idea to update more frequently. Three to four per year will allow you to enjoy the latest maps and get to your destination without any unpleasant surprises. There are other special circumstances that may prompt you to download a new map or update your GPS. For example, you plan to move abroad or go on a trip to another country. If you only had France mapping planned when you purchased your navigation system, you will need to install a new area. Some events may also cause you to update your device.

Update your GPS system for free: how to do it? For example, changing the current speed limits and changing from 90 to 80 km/h on two-way roads is a good reason to update your system. Updating a navigation system is often not free of charge. In most cases, you must purchase the update or take out an annual subscription. However, when you have already invested in a GPS that costs a certain price, it is not always easy to systematically put your hand back in your pocket.
