My car isn’t accepting my new Apple IPhone 13 using the customary Bluetooth and it appears MB are not yet up to speed/date with this latest IPhone connectivity so where do I go from here to correct this do you think ….? Buy a newer Mercedes’ ?!

Hi Fruityquery,

We understand that you're unable to connect your iPhone 13 to your car stereo via Bluetooth. If you haven't already, check out the steps below from the following article, to see if those help: How to connect your iPhone, iPad, or iPod touch to your car - Apple Support

"Connect using Bluetooth

1. Restart your device.
2. Go to Settings > Bluetooth, and turn off Bluetooth. Wait for about 5 seconds, then turn Bluetooth back on.
3. Check the manual that came with your car for more information on how to pair with a Bluetooth device. Most cars require a phone setup on the car display. 
4. If you've connected multiple phones to your car stereo, try renaming your device: Go to Settings > General > About > Name, and type a new name. Then try connecting again.
5. Update your device.
6. Make sure that your stereo is using the latest firmware from the car manufacturer. Check your car's manual for more information.

If you still can't connect, contact Apple Support."

Best wishes to you.

Fruityquery,

We're glad that the issue has resolved itself, without the need for a Bluetooth booster. Thank you for using Apple Support Communities!

Cheers.
