Just wanted to update everyone - Ended up going with the 700IDT because a forum member here sold it new for a great price. All in all, the install is going really well.
The big problem right now it cramming the Eclipse CD4000 and the Xenarc 700IDT into the double din opening in my tC. I have filed my OEM brackets so the little mounting nubs are gon, thus allowing the TouchScreen to actually fit with minimal bowing to the OEM Din brackets (its a -tight- fit).
While it fits in there, it pokes out far enough that I just can.t seem to get the plastic face of my dash to go back on. I believe the suspect is that whether mounted on top or bottom, it is still bumping somewhere. I also think that I may have to remove the door which closes over the DblDin hole (not a big deal)
Anyone have any experiance with this especially if you have a tC? For now, I'm going to try and modify the very flimsey plastic din Crutchfield supplied with the HU and maybe give me more options.
and a final thought, the 2 metal 'U' pieces sticking out the back of the Xenarch TS, do they do anything? Can they be removed so I can get more depth?
