I bought the Dynavin N7 Pro about a year ago and had it installed by an audio shop. Total for the HU, BU camera, Sirius mod and installation of all was about $1,500. So far it works well. The new wireless model should be an improvement. A volume knob would be better but the 2 buttons for +/_ volume work well. The BU camera works great and is very useful when backing out of driveway where kids can be behind the car at any time.
