my sony xperia aqua phone contacts won't transfer to my citroen c5 bluetooth

[AC Question]

I connected my sony xperia aqua phone to my 59 reg citroen c5 bluetooth and all the contacts came over too. Recently my key fob stopped working to I reset it on my car then had to reconnect my sony xperia aqua phone to my car bluetooth, now the contacts will not come over and when someone rings it does not save their number on my car bluetooth. Can anyone help me please.

Hi, has anything changed on the phone, did you recently update it or anything like that? did you follow the exact same steps taken in the first place when re-connecting the device?
