Hi isj1,
We'll be happy to address this with you. If you're only experiencing issues when connecting to the car, then you'd need to reach out to the manufacturer for further assistance.
We'd also make sure you're following the pairing process exactly as outlined in Pair a third-party Bluetooth accessory with your iPhone or iPad - Apple Support
"Pair your device with a Bluetooth accessory
- On your device, go to Settings > Bluetooth and turn on Bluetooth. Stay on this screen until you complete the steps to pair your accessory.
- Place your accessory in discovery mode and wait for it to appear on your device. If you don't see it or aren't sure how to make it discoverable, check the instructions that came with your accessory or contact the manufacturer.
- To pair, tap your accessory name when it appears onscreen. You might need to enter the PIN or passcode. If you aren't sure what your PIN or passcode is, check the documentation for your accessory.
After you pair your accessory, you can use it with your device. To pair multiple Bluetooth accessories, repeat these steps. If you have multiple Bluetooth devices paired with your iPhone or iPad, you can choose which audio source you want to use."
Cheers.
