I've searched the forums already and all the bluetooth threads are years old at this point, so having just bought an '05 S40 I'm looking to find out what the current options for adding bluetooth (for handsfree calling) to my car. It's a 2.4i (not sure that matters) and it has the premium sound package. The dealer quoted me $560 installed this morning and that sounds a little steep, so I'm hoping there are other options out there at this point.
