I know this sounds nuts but I like the Nav. system that comes with the 300C. Well, that's not nuts, but putting it in my Miata might be. I thought about the Eclipse in dash system but a Miata is the last car I'd put something like that in. Would take all of 30 seconds to lose 2 grand of stereo not to mention the top, trim, and wiring that would get cut and broken. I guess the question is, if I can figure out the wiring would it be possible to do this? I know it would be easier to put anything aftermarket in, but the unit would look factory and without a name like Alpine or Eclipse on it I think it just might get looked over. My dash has a double-DIN opening so fitment shouldn't be an issue. Other than that, I've not seen this done before and thought it might be fun to try. It's an expensive idea, but if it works it will be well worth the money spent. I know its probably the dumbest thing you guys have read in a while but tell me what you think. Thanks. Jess
