[s-cars] Built in phone - 93 S4

[Bill Mahoney]

The oem analog phone is an ancient relic.  
If it is working, it wont be long before the signal is stolen and you'll
have a zillion calls to mexico. BTDT.  
I have this Bluetooth hands free in the A8.  Its wired into the head
unit and provides muting to the radio and sound though the oem b pillar
speaker.

Could easily integrate into the s4/s6 bose too I think.  

In the S6 I just use the Jabra wireless headset with a Bluetooth phone.
Just bring a Bluetooth phone within I think its 10 feet of the receiver
(i.e. into the car) and it will be automatically and magically
connected.
Very nice.
