If there is no network connection, check if this device has malfunctioned. It is recommended to turn it off and restart it. Below is an introduction to the BYD Song: 1. BYD Song: Positioned as a new energy compact SUV, it features an X-shaped front grille, giving it a sporty appearance. On the side profile, the vehicle adopts hidden A/B/C pillar designs, creating a floating roof visual effect. 2.

In terms of dimensions, the BYD Song measures 4565/1830/1703mm (L/W/H) with a wheelbase of 2660mm. 3. Powertrain: The BYD Song is equipped with a hybrid system consisting of a 1.5T engine and two electric motors, with one motor positioned on the front axle and another on the rear axle to enable four-wheel drive functionality. Additionally, the BYD Song offers a pure electric range of 70km and accelerates from 0-100km/h in 4.9 seconds.

I've been driving the BYD Song for a while and have encountered similar issues. When the BYD Song has no internet connection, it's usually related to several reasons: First, it could be an issue with the in-car SIM card—if you haven't topped up or the card isn't activated, the network naturally won't work. Second, it might be a signal coverage problem, such as in tunnels or remote mountainous areas where weak signals can cause disconnection. Third, the vehicle's infotainment system might need an update, as older software could have bugs. Fourth, incorrect network settings, like accidentally turning off mobile data, could be the culprit. I remember once on the highway, the internet suddenly cut off, and I later found out the SIM card had expired. I suggest trying to restart the infotainment system by holding the power button on the center console for a few seconds—sometimes this can fix temporary glitches. If that doesn’t work, take it to a 4S shop for a technician to check the SIM card and antenna connection to ensure everything is working properly. It's also good practice to regularly check the vehicle's network status to avoid issues with navigation and entertainment features.

This is a pretty common issue, and I've tried many infotainment systems. If the BYD Song has no network connection, the reasons likely lie in settings or hardware. First, check if the mobile data option is enabled in your infotainment settings - sometimes it gets accidentally turned off. Second, verify if the SIM card has active service. BYD vehicles usually come with built-in SIM cards, so make sure the card isn't overdue or deactivated. Also, software updates are crucial: newer versions might fix bugs. If you're getting weak signals, try driving to an open area to see if it improves. Rebooting the system often helps: press and hold the volume and power buttons for ten seconds, then release and restart. If the problem persists, it might be an antenna malfunction requiring repair. Remember to stay calm when troubleshooting - find a safe place to park before making adjustments.

When the BYD Song experiences network interruption, the basic issues generally focus on three areas: first, the onboard network module may malfunction, such as loose or damaged antenna interfaces; second, signal issues from the provider, where unstable network coverage causes disconnection; and third, internal system errors requiring a reset. I recommend starting with simple checks: ensure the vehicle is in an open area, start the engine to see if the network resumes. If there’s still no connection, try turning off the vehicle, waiting a few minutes, and then restarting to reinitialize the system. Sometimes this can temporarily resolve software conflicts. For a permanent fix, professional diagnosis is needed—visit a repair shop to scan for and rule out hardware issues with specialized equipment. Safety first—avoid operating while driving.

As a family car owner of a BYD Song, I've also experienced network dropouts. This could stem from daily oversights: for instance, unpaid SIM card fees leading to service suspension; or parking in a garage where signals are blocked. Remember to check if the network settings accidentally disabled data options; additionally, the vehicle system might require a software update to optimize network connectivity. Once during a long-distance drive, unstable network occurred due to passing through signal dead zones, but it normalized after restarting the infotainment system. Timely resolution is advised to prevent navigation and safety impacts. Always address such issues in a safe location—don't let minor issues escalate.
