Changan CX70's infotainment system can be upgraded. The method is as follows: 1. First, download the upgrade package software for the infotainment screen to a USB drive; 2. After starting the vehicle, shift to neutral (N), and insert the USB drive into the USB port; 3. The display screen will show the software upgrade information, click to upgrade. The Changan CX70 is a mid-size SUV with body dimensions of: length 4680mm, width 1800mm, height 1775mm, and a wheelbase of 2780mm. It is equipped with a 1.6L naturally aspirated engine, delivering a maximum power of 86kW and a maximum torque of 150Nm, paired with a 5-speed manual transmission.
Recently helped a friend research the infotainment system upgrade for the Changan CX70, and this matter needs to be broken down. The factory did release system update packages, and older owners can inquire at 4S shops, but models after 2018 have basically stopped receiving updates. If you want to do it yourself, be cautious—you can find cracked system versions online, but flashing carries risks. I've seen cases where the reverse camera stopped working after flashing. A safer approach is to install a CarPlay box, which can be done for just over 200 RMB on Taobao—just plug it into the USB port to mirror your phone's navigation on the infotainment screen. If the system feels sluggish, don’t rush to upgrade—try entering engineering mode to clear the cache or restore factory settings first; the effect is immediate.
I personally upgraded the infotainment system on my CX70, which involves both hardware and software modifications. Software upgrades are relatively simple—Changan's official website released a V1.3 firmware package that can be installed via USB, but it only supports the 2017 model. For hardware upgrades, you'll need to dismantle the dashboard, so it's best to have it done by a professional shop. Spending around 800 yuan to replace it with an Android touchscreen also allows for adding a 360-degree camera. A special reminder for modders: avoid overly powerful audio equipment, as the stock wiring can't handle it—my colleague's head unit had its motherboard fried by a subwoofer. Honestly, the most practical thing about the factory head unit is regularly clearing junk files, and using a phone mount for navigation is much more convenient.
