Just by way of information, of little relevance really, I have owned the following Volvo's:
I have had one minor issue with my C30 and that was getting it to pair via Bluetooth with a Samsung Galaxy S3 Mini running Android 4.1.2. It would connect, establish a connection and then try to get the connection sorted but the audio system would keep cutting out. In the end I found the trick was to turn off the "Audio Connection" on the phone. This means the car is quite happy with the phone for calls etc but I cannot send music to the car from the phone via Bluetooth, which is no loss for me!
Update: all of the above was on 09.11_R of the Bluetooth module. When I had this updated to 09.14_R the music issue went away. It is also worth noting that 09.11_R is not compatible with the Windows Phone 8 Black update, aka GDR3, however 09.14_R also fixes this.
