07 DB9 Phone Button on Radio Not Working

[Kynitekia]

Hi all. Recently acquired an 07 DB9 Volante with only 14k on the odometer after selling my 08 V8V. Everything seems to function (hurray) except for the "Phone" button on the top left of the radio unit by the power button. Pressing that does nothing and I am unable to get into any phone menu's or use the radio buttons for dialing. I was able to pair my phone with the steering wheel voice command button, however.

Any suggestions on this?

Thanks!
