The Eclipse all-in-one unit has a poor laser eye for reading CD/DVD etc.. from what I have heard. Breaks down and doesn't work at all after some time.
If you looking for a all-in-one unit (I am too) have a look at Kenwoods DDX-7045 unit. Pricey but damn good. I've being eyeing this unit for the last year or so, but they keep updating them with more good features all the time, not helping my cause as I keep thinking the next update will be better. One thing, as you and I have the same Sat Nav unit :s6: the remote has to be in it's cradle and hard wired permanently, can't use freely like you do now. If you plan to have the screen mounted seperately, then no probs, you can you the sat nav input for something else, maybe reverse camera?
Here's a pic:
Kenwood's Aussie site doesn't have much info on this unit. Do a search on some overseas reviews, pretty good unit I must say.
