The car never "asks again"
As long as the bluetooth is active on my phone it syncs up automatically but with limited numbers....it just sits in my pocket.
not the car "asking again"
Your Phone, the Galaxy Ace "asking again" to give permission to access the phone book, every time it connects to the SEAT bluetooth.......
If the phone does, then on then message on the phone there is a check box to tap that says "dont ask again"
I had the same issue with my Galaxy S3:
i'd turn on bluetooth on my phone,
phone connects to car bluetooth
everytime i did so, the phone gave a 'chirp'
message on phone was 'SEAT BT wants access to your phonebook, give access?'
I tap yes on the phone screen
soing so, sometimes my phonebook would load up & appear on my MFD & sometimes it wouldn't sync my contacts
However, i noticed that in addition, on the phone message, there was a little 'tick box' on the on screen prompt, with "dont ask again" next to it
so i checked the box
since doing so, my phone no longer 'chirps' when it connects to the cars bluetooth and it automatically synced all the phonebook and it now loads up all my phone contacts & these appear on my MFD evertime with no issues
does that make sense?
