I have the Eclipse AVN 5435 Double Din with Navi, DVD, touchscreen, etc... I installed it myself in my 2000 X5 with the DSP system. As far as fitment it sides right in after you cut the bracket that seperated the top and bottom OEM headunits. Wiring is another story. I ended up replacing the DSP with a new amp and sub. It was much easier, for me, then trying to wire around the dsp componets. Also selling the OEM DSP amp and Sub paid for most of the cost for the new equipment. Goodluck!
