The AVIC-D3 comes with just the D3 HU. AVIC-D3X comes with the D3 HU, bluetooth adapter, remote, and ipod cable. AVIC-D3Y comes with the D3 HU and the bluetooth adapter. 3 different packages, 3 different prices. Not sure which ones BB sells, but they are overpriced. I just got the D3Y package from abt.com for $595, but I just looked it up to link here and it is missing. Seems the D3 inventory is really drying up with the F-series coming out soon.
