1. The most convenient way to find after-sales service

　　When it comes to how to upgrade a navigation device, calling the after-sales service of the product is the simplest way. Currently, many brand navigation devices have adopted a free solution for the upgrade part in order to further expand their market share. This means that users do not need to spend any money on upgrading their navigation devices, so we do not need to search for resources to upgrade ourselves.

　　We can first divide the general navigation system upgrade into two situations: one is the official free upgrade, and the general official free upgrade navigation software is divided into two types: general aircraft software and brand specific aircraft software.

　　Even if the upgrade of the former navigation system is free, we still need to go to a after-sales service point to upgrade. This includes Kailide, Daodao Tong, and some common general-purpose software versions. Depending on the marketing strategy of different manufacturers, the cost and method of upgrading may vary. That's why there is a significant difference in the upgrade costs for the same Kailide software on the market.

　　The latter usually launches dedicated management software, and users can wait for the new version of software and data to be released, download and connect to the navigation device installation on their computer to complete the navigation device upgrade.

　　Regardless of the method, it is best to use official channels to upgrade the navigation system in a closed system. Most users do not have access to the corresponding cracked version resources, and the cracked version software needs to modify the configuration file. Users may not know where to start from.

　　2. Mainly 4S stores

　　Generally, there are two types of navigation device upgrades for car infotainment systems. One type is the original car infotainment product, which does not require our introduction and must be upgraded at the original 4S store to avoid damaging the warranty when upgrading the navigation device for original items. Another type is the afterloading machine product purchased by users themselves, which is relatively easy to upgrade.

　　The old version of car infotainment products did not reserve interfaces such as SD cards for easy upgrading, which resulted in the need to connect specific USB or other devices to write new data into the product when upgrading; New car products produced in modern times can be upgraded using SD cards, and corresponding upgrade cards can be purchased at 4S stores.

　　3. The new product is temporarily not needed

　　We can explain the upgrade of intelligent navigators in a simpler way. We believe that users with strong hands-on abilities will search for cracked version resources to upgrade on the internet. Because the application startup program of the intelligent platform is separated from the data packet, and after the application is cracked, it can be paired with the data packet to allow the navigator to enjoy the cracked version of the software for free. Relatively speaking, it is much simpler than upgrading the navigator from official channels.
