Hi Everyone, I have 1 gripe about my RX 450h Advance after 1 month of ownership is the lack of DAB. Sure it has a 6 CD changer, AUX & BT Input but I really miss the DAB Radio. Can anyone give any insight to upgrade options? Is anyone breaking a vehicle with DAB that will fit a 2012 RX? Ive also seen BT units online as an add on. Has anyone tried this option. Thank you for your time and advice Ade
