In-car data usage is free for the first two years, after which it will be charged. Car charger: A car charger refers to a conventional charger powered by the car (12V for cars, 24V for trucks), widely used in the charging of lithium batteries for various portable and handheld devices. Precautions for using a car charger: Charging should only be done when the car engine is started. Do not use the car charger in a humid environment or store it in such conditions. The suitable operating temperature range is 0 to 45 degrees Celsius. Keep it away from children and unplug it promptly after charging is complete.

When I first bought the Bestune B70, I was also puzzled about whether the data traffic costs money. Actually, it can be divided into two parts: the built-in Gaode navigation and remote control functions use lifetime free data traffic. Last winter, I used this feature to preheat the car in the garage without consuming my phone's hotspot. However, for entertainment purposes like listening to music or watching movies, I was given a 6GB monthly data package for two years when purchasing the car, which was enough for daily commuting with NetEase Cloud Music. A few days ago, when the data package expired, I checked the renewal pop-up in the Bestune YOMI app and found that the three-year music package for 398 yuan is quite reasonable. It's much more stable than using a hotspot, at least the navigation won't drop and make me take a detour.

A veteran driver who has used three generations of car networking tells you: The key is what you use the data for. Safety services like remote unlocking and vehicle positioning come with free lifetime data from the Bestune manufacturer—tested it myself unlocking the car door for family at midnight, works great. But for streaming Douyin or live broadcasts, you'll need to top up your own data package. Tapping 'Entertainment Center' on the central screen brings up the pricing page—35 yuan for a 6GB monthly package, a bit pricier than mobile data but with more stable signals. Last week, I binge-watched shows on a mountainous national highway without any lag. Pro tip: Connect to your hotspot as a stopgap when you get the new car, then wait for a 4S store promotion to buy the data package at a 20% discount.

There are three scenarios to consider: First, system upgrades and basic service traffic are free. My car's infotainment system has received three OTA updates without any charges. Second, the vehicle purchase includes two years of entertainment data. I listen to Himalaya for two hours daily, which fits perfectly within the allowance. Third, for renewal, I recommend the annual package. In the Bestune app, go to 'My Account - Data Store' and select the 198 yuan/year option, which works out to just 50 cents per day. If you ever run out of data, don't panic – you can always connect to your phone's hotspot for navigation.

Actual tests reveal that the Bestune B70's data traffic is divided into three pools: vehicle control traffic is free for life, navigation map updates are free for the first five years, and music streaming traffic comes with two years upon purchase. Last month, I specifically checked page 83 of the 'Owner's Manual,' which clearly states 'audio and video entertainment requires purchasing a data package.' By tapping Settings-System-Traffic on the central control screen, you can view real-time usage. For office workers like me, 4GB per month is sufficient. The new policy is even more generous now, with rumors suggesting that the 2023 model offers even basic traffic free for life.

I helped my colleague set up data for his Bestune B70, and here are three key takeaways: First, the built-in emergency call feature in the car's system is always free of data charges. Second, avoid purchasing data plans through the car's store; instead, download the Bestune YOMI app on your and go to 'Services - Data Top-up' for cheaper options. Third, it's better to connect to your phone's hotspot for video streaming. Last year, he exceeded his data limit watching a soccer game and was charged an extra 80 yuan. For specific pricing details, check the 'Smart Enjoy Package' page on the official website—it's very transparent. Surprisingly, real-time traffic updates for navigation don't incur additional charges.
