Hello all.

Just registered to ask this question:
i have an audi A4 avant that is a little bit less than 1 year old.
i have been using my iphone with bluetooth since then without problems. I use voice recognition to state the callers name and everything was working as intended.

2 days ago, i gave a friend's name, i call him regularly without problems and the voice recognition system tells me there is no one with this name. i try again, same result.
i use my phone to select the guy's name and call him and his name doesn't appear on the interface of the car as it does with people with a name. it's just a number.

it appears that the car lost the definition of some people in my contact list, not all of them. i can call my mom, but not some of my friends.

the car did not go to the garage so i guess theres no change there.
i did not update my phone
i remember falling asleep while typing on my phone and when i opened my eyes i was in the bluetooth menu with the connection of the car opened, but i don't think i clicked anything... yet, just to be sure, i erased the bluetooth connection on my phone and redefined my car as usual, but it didn't solve the problem.

Does it ring a bell to someone ?
would there be a reason for loosing some names, but not all of them?
so far i only lost 3 names, but the 3 names had just 1 number (no selection of mobile or house phone after the name) so i don't know if it's a pattern or not ...

can someone guide me towards an action to solve that?

thanks
