Probably a Tesla bought privately would have been wiped by the seller, but if it was a trade-in it might reasonably be expected that a dealer would include all that in the prep ?

Presumably the previous owner had the car had it synced with his phone. I think the Skoda can import my contacts but not much else. My daughter has hers set up in her Octavia and car has microphone to facilitate hands free and I assume Fabia has same functionality. Not bothered with it as I rarely use the phone in the car and am content to put it in a clip and use a blue tooth earpiece on odd occasion I do.

If I did have stuff like that I hope I'd remember to clear it when trading in. If I'd forgotten or not been able to I'd expect the dealer to do it not allow my details to be visible to the new owner. Same as I'd expect a reconditioned PC or phone to be wiped.

Would be interesting to see what the Information Commissioner has to say should a complaint arise.

Iirc I think you have to do a factory reset of the computer on the dash as it retains all info you put on it, encrypted as well.

you can do that on standard infotainment systems as well.some hold phone nos and addresses in certain cases, so factory reset clears all of it

When you link an Android phone to our Fabia (2018 SEL) by USB to use Android Auto it does indeed download contacts. There is a microphone symbol but never tried it.

I never make calls when I am driving even though its hand free, you can actually access contacts through the steering wheel buttons so no need to wave your fingers aimlessly at the display. Actually never answer calls unless its from the Mrs, she knows only to phone if its critically important, anything else a text will do.
