CarPlay stops after 2 tot 3 minutes

If your vehicle is equipped with only USB-A ports then this would appear to be a cable chipset issue. Newer OEM cables utilise a chipset that facilitates fast charging and broader communication capabilites between devices; ie USB-C type cables. USB-A type cables do not. After some fairly extensive testing it has been found that only USB-C OEM cables or the aftermarket equivilent (that carry a C89 chipset) are 'capable' enough of handling CarPlay function on newer, higher powered handsets on certain vehicles. If you are attempting to use CarPlay from a newer handset with an older USB-A type cable, it is likely to overload its capability and cut out after just a few minutes requiring a disconnect/reconnect to re-establish communication (only for it to then cut out again a few minutes later).

As for options, you can try:

• Updating software/firmware on both devices.
• Replacing your older USB-A cable with a newer version equipped with a C89 chipset.
• Adding a USB-A to C converter and using the USB-C cable that was supplied with the handset.

If you're willing to give any of these a try, let us all know how you get on.

Hello RPBossie,

It sounds like you're having issues using CarPlay with your iPhone 14 Max. In these cases, we'd take these steps, since they are relevant to your issue: If you need help with CarPlay

If CarPlay doesn't work like you expect, learn what to do.

First, make sure that your country or region supports CarPlay and that your car supports CarPlay. If you're unsure if your car supports CarPlay, contact the vehicle manufacturer.

Make sure that your iPhone has the latest version of iOS. If your iPhone is updated to the latest version of iOS, follow these steps—checking CarPlay after each step:

1. Check your connection to your CarPlay stereo:

* If you have a wired connection, try connecting again with a different USB cable to a different USB port if you have one.

* If you have a wireless connection, make sure that Bluetooth is turned on on your iPhone under Settings > Bluetooth. Then go to Settings > Wi-Fi, and make sure that Wi-Fi is also turned on. Tap the CarPlay network, and check that Auto-Join is turned on.

2. If CarPlay doesn't activate automatically, look for the CarPlay logo on your car's display and select it.

3. Restart your iPhone and your car. 

4. Make sure that Siri is on.

5. If your iPhone isn't detected by CarPlay, make sure that CarPlay isn't restricted. Go to Settings > Screen Time > Content & Privacy Restrictions. If Content & Privacy Restrictions is on, tap Allowed Apps, and make sure that CarPlay is enabled.

6. Go to Settings > General > CarPlay, tap your car, then tap Forget This Car. Then set up CarPlay again.

7. Make sure that your CarPlay stereo is using the latest firmware from the car manufacturer. Check your car's manual for more information.

If you still have issues connecting to CarPlay, contact Apple Support.

As mentioned at the end of this resource, if you continue to have issues using CarPlay, then it would be best to contact Apple Support directly: Get Support They'd need to take it from here.

Take care.
