1. First, let's upgrade a software version. After all, you need software to put it in the map. For example, upgrading from version 7.0 to version 8.0. One way is to use some application management software, such as app store, itunes or sync assistant. Go directly to the software update page and click Upgrade. However, because the navigation software itself does not contain a map, the update of the software may not enter the update recommendation page. At this time, all we have to do is directly search the software, download and install it. This will ensure that nothing is lost.

2. After the software is installed on our Apple device, let's add the required map. Run the navigation software and the map download page will appear. There are two options, one is to download it by computer and then pour it into the device. The other is that in the WIFI environment, the device downloads directly. This requires a high speed wireless network.

Because the size of the map is several g, we don't need to download the map of the whole country, just the map of the area we need. For example, I only downloaded the "Map of East China" for Jobs. Remember, if you use WIFI to upgrade and download the map, you should restart the navigation software after downloading.
