I just installed a Sony XNV-770BT in dash Nav/Receiver with bluetooth capability in my vehicle. Both my wife and I have the iPhone 4S with AT&T. The caller id name/number will show up on the iphone, but will not pass through to the Sony unit, until after you answer the call. (This of course defeats the whole purpose of caller id!) Before you answer the call it says "Withheld", which is the Sony term for blocked, I guess.
It seems that there are quite a few issues with various iphones not passing the caller id info through to bluetooth devices, but I have not been able to find a solution to my specific problem. I called Sony and they offered to send me a new unit after I remove the one I just installed and return it to them, because they said the caller id feature is supposed to work with the iphone 4s. But this is a lot of trouble to go through only to find out the new unit acts the same way and it is really an iphone issue. The caller id pass through does not work with either mine or my wife's phone - I did the recent iOS 5.1 update and my wife has not.
Here are the bluetooth profiles that the Sony unit supports:
Compatible Bluetooth® Profiles : A2DP (Advanced Audio Distribution Profile)1.2
AVRCP (Audio Video Remote Control Profile)1.3
HFP (Handsfree Profile)1.5
OPP (Object Push Profile)
PBAP (Phone Book Access Profile)
We also downloaded our phonebooks into the Sony and and it does not make a difference if the call comes from a phonebook contact or not...
