I've just bought a 2009 2.0 tdi SE Golf. It has the Rcd 310 and I want to add Bluetooth. I've read about adding the module under the passenger seat, but all references I've read talk about answering a call using the steering wheel controls. I don't have these so can I answer calls using the stereo unit instead? If not is it pointless getting a Bluetooth module? Also, if it does work, do the caller's details appear on the driver display panel (between the rev counter and speedo)? Thanks
