Why does this happen?
Wireless CarPlay uses Wi-Fi + Bluetooth to connect your iPhone to your car.
Your Dash Cam also needs Wi-Fi to connect to the Nextbase app.
Your iPhone can only connect to one Wi-Fi device at a time.
This means your Dash Cam app won’t connect until you temporarily turn off CarPlay.
How do I temporarily disable CarPlay?
On iPhone, go to Settings > General > CarPlay.
Select your car from the list.
Tap Forget This Car – this disconnects wireless CarPlay.
Now connect to your Dash Cam's Wi-Fi network via the Nextbase app.
Your iPhone will now disconnect from wireless CarPlay, letting you join your Dash Cam’s Wi-Fi network.
Reconnecting CarPlay after you’re done
On your iPhone, plug into the car with USB (or reconnect wirelessly if supported).
CarPlay will set up again automatically.
Extra tips
Use a wired USB connection for CarPlay if your car supports it. This frees up your iPhone's Wi-Fi for the Dash Cam app without conflicts.
Connect to your Dash Cam first during setup or app use, then switch to CarPlay only when needed.
Check your iPhone's Bluetooth settings too – turn off car Bluetooth temporarily if Wi-Fi alone does not resolve the issue.
Make sure the Nextbase App is up to date.
Troubleshooting
If this still wont connect after forgetting CarPlay, restart your iPhone, reopen the Nextbase app, and try joining the Dash Cam's Wi-Fi network again.
If you are experiencing frequent dropouts during use, move your iPhone closer to the Dash Cam and ensure no other Wi-Fi devices are interfering.
Issue persists on iOS updates: Check Apple's support site for CarPlay changes, update the Nextbase app, and contact Nextbase support with your iPhone model, iOS version, and car details.
