I paid $465.00 for the stereo and all required hardware to install it. I had the ASWC-1 module already from a previous vehicle but I believe they are about $80.00 (Canadian Tire used to sell them for $40.00). The link is below but they can be purchased from various places online.

As a side note - Nissan (like many auto manufacturers) uses 2ohm speakers and almost all aftermarket radios are 4ohm. Therefore, if you listen to music loud, the radio will cut out at higher volumes unless you change the speakers to 4ohm, which I ended up doing as well.
