Thanks, tho not clear how to do that. This was prompted by rental agency, guess they don’t want final buyer to see list of previous users. Not happy about that either.

Not clear how to do what?

Check the car's manual? It standard for car rentals to keep the car's owner's manual in the glove compartment of the car.

But as said, in general downloaded data such as contacts does not get saved onto the head unit. Once the car is turned off the data is deleted, and redownloaded the next time the car is turned on and the phone is connected to it. Only thing left to do is to Forget the paired iPhone before returning the car, and again that will depend on each car.

An easy way to find out how to forget devices is to search in Google or your search engine of choice for the make and model of the rental car and the words "forget paired device". That should produce relevant results.

tntoofore,

No personal data should be stored on the car.

If you wish to remove the name of the phone from the car's list of previously paired phones, reverse the steps that you used to pair the phone initially. The steps will vary by make of the car.

Good luck.

Depends entirely on the car. Each car head unit is different. You would need to consult the car's owner's manual to find out how to unpair, and delete all downloaded data from the head unit in car.

There is nothing you can do from the iPhone itself.

Do note, that in general downloaded data to the head unit is not kept in the head unit itself once the car is turned off. But for more specifics you will need to check the media center's manual for the car in question.
