I just bought my 2012 Fiat 500 sport a week ago. I have an iphone 4.
When I connect the usb and the phone to the car I can use my music. However, I have tried several times to pair it with Blue&ME so I can use the handsfree phone function.
When I open the bluetooth in my phone settings I can see the device "Blue&Me", the car will give me a pin code but when I click the Blue&Me device I get this message:
"Connection Unsuccessful. Make sure "Blue&Me" is turned on and in range."

Please help
Also, my iphone 4 is up to date with iOS 6.1.3

Probably no help to you but my iPhone 4 pairs up happily with blue n me....
