I ended up with an Alpine 126BT (Bluetooth, remote ready, USB, Aux and I-pod connection. Replaced and upgraded all speakers - sound is great but still lacks a little punch in the bass - Will now add a sub and a small amp to power it. Radio has sep. subwoofer control.
Radio ergonomics are good and the install is clean - not to flashy. Could not find a Nakamichi dealer around.
