# Built-in car hotspot setup
|
|
|
|
DiAuto & DiPlay — Built-in car hotspot test builds
|
|
28 September 2026
|
|
|
|
DiAuto-connection-setup-test.apk: Android phone / Android Auto
|
|
DiPlay-connection-setup-test.apk: iPhone / Apple CarPlay
|
|
Install the APK on the car, not on your phone. Update the matching existing
|
|
test app without uninstalling to preserve settings.
|
|
|
|
These builds remove the Local hotspot option. Built-in car hotspot is the
|
|
default; Wi-Fi Direct and USB remain available. Previous Local hotspot
|
|
selections switch to built-in hotspot. Check and save the car's real hotspot
|
|
details before connecting.
|
|
|
|
BUILT-IN HOTSPOT SETUP — BOTH APPS
|
|
1. In the car's settings, turn on its built-in Wi-Fi hotspot. Select 5 GHz
|
|
if available. Note the hotspot name and password exactly.
|
|
2. Open DiAuto or DiPlay on the car. Go to Settings → Connection setup
|
|
(tap Open connection setup if shown).
|
|
3. Select Built-in car hotspot. Tap Save hotspot details and use this mode
|
|
(or Edit saved hotspot), enter the car's hotspot name and password, and
|
|
save. Use Hide keyboard if needed. Leave the car hotspot on.
|
|
4. Turn on Bluetooth and Wi-Fi on your phone. Pair it with the car's
|
|
Bluetooth. Allow the app permissions requested on the car.
|
|
5. Return to the app and tap Connect phone. Select your phone when asked.
|
|
In DiPlay, use Choose iPhone if you need to select a different phone.
|
|
6. Accept the Android Auto or CarPlay prompts on your phone.
|
|
|
|
You do not need to join the hotspot manually on your phone before tapping
|
|
Connect phone. The app sends its details over Bluetooth so the phone can
|
|
join automatically. Use the car's hotspot, not your phone's Personal Hotspot.
|
|
ADB is not required for this connection setup. A car internet plan is not
|
|
required; phone internet availability depends on its network settings.
|
|
If you change the car hotspot name or password, update it in the app too.
|
|
Test one projection app at a time.
|
|
|
|
OPTIONAL: DIPLAY AUTOMATIC INSTRUMENT MAP
|
|
On the supported DiLink 5.1 firmware, open Settings → BYD navigation →
|
|
Automatic map setup · ADB. Follow the displayed one-time computer setup,
|
|
then tap Check and enable. Open the cluster's map card or select Map theme.
|
|
This permission is for automatic cluster theme/card detection, not hotspot
|
|
connection. The guide explains the exact command for the installed app.
|
|
|
|
WHAT TO TEST / REPORT
|
|
Check first connection, reconnect after restarting the app/car, maps,
|
|
music/audio, and any instrument-map features supported by your car.
|
|
If something fails, note the time and steps, car model, DiLink/Android
|
|
version, phone model/OS, and which app you used. Export a diagnostic report
|
|
from Settings → Diagnostics → Save diagnostic report. Reports are saved
|
|
under Downloads/DiAuto or Downloads/DiPlay. Share the report with your test
|
|
feedback; do not include your hotspot password.
