OWNER ANSWER
BYD sat-nav location wrong after an update?
First identify which map is wrong: BYD’s built-in navigation, Apple Maps or Google Maps on your phone. For a built-in map showing the wrong position after an update, try the owner-confirmed display restart and open-sky GPS check below. If the phone map is also wrong on the handset, check its location settings before resetting anything in the car.
- Park in an open area with a clear view of the sky.
- Check whether the wrong map is the car’s native navigation, Apple CarPlay or Android Auto.
- Once the OTA installation has finished and normal controls are available, use the display restart documented for your model. Safety note: Wait until installation has completed before restarting, and use the screens only while parked. Interrupting an update or troubleshooting on the move creates a separate risk.
- Wait for the home screen to finish loading.
- Leave the affected navigation open for several minutes and check its position.
What to expect
The affected navigation locates the car correctly after normal start-up in an open area. If only the phone map remains wrong, identify that separately from the built-in navigation.
If that did not work
- Only the built-in BYD map is wrong: check for a matching vehicle or map update, then ask BYD to investigate the persistent location fault. Give the map name/version, full vehicle software and restart result.
- Apple Maps is also wrong on the iPhone: open Settings → Privacy & Security → Location Services. Enable Location Services and give Maps access While Using the App or Widgets. Check Date & Time and an active Wi-Fi or mobile-data connection, then close and reopen Maps.
- Google Maps is also wrong on Android: tap Your location in Maps. A grey or absent dot means it cannot find the current location; a large blue circle means uncertainty. Follow any location-accuracy message, check Location services and the phone’s Location Accuracy setting, then recheck outdoors with a clear signal.
- The phone map works but will not appear on the car: use the matching CarPlay or Android Auto connection guide below. That is a different symptom from an inaccurate location.
If it remains wrong, tell support which map is affected and whether its marker moves, observed after parking or by a passenger during an ordinary journey. There is no need to make a special journey to reproduce it.
What this helps separate
A native map that is frozen or in the wrong place is different from a phone-map location problem. CarPlay and Android Auto do not necessarily use the car’s location source. The restart and open-sky sequence is owner-confirmed; keep that comparison separate from a diagnosis of the GPS receiver.
