I'm replacing the HU in my 2000 Mobius. It has the stock Kenwood KDC-3022 deck. Will most HUs fit in the same slot and allow me to use the slide down cover? I'm leaning towards the Sony CDX-M60UI at the moment, but would like any suggestions that you may have. FYI, I have an 80GB Zune that I keep my tunes on. Is there even one Zune ready HU out there. I love my Zune, but it sucks that everything is made for the Apple products only.
