I think you will also need an Antenna adaptor (I believe this is the correct one -- Metra 40-NI12. Crutchfield says it is)
Antenna Adapter Works with select 2006-up Infiniti, Suzuki and Nissan vehicles (Motorola male to OEM antenna female) at Crutchfield.com
Also, a question on the Double Din Faceplate -- do you only need it if you have the Bose system? I have a 2013 Base model, and the faceplate looks already to be sized for a double din unit.
