eclipse head units, at least in my experience.. are overpriced crap boxes. i've had 2 5442's in 2 different vehicles, and i make pretty long trips almost every week or every other week *(2 solid hours of driving)* and they would get HOT.. when i say hot, i mean hot enough to burn the edges of the cds. they also would chip off the top layer of cd art on non-store purchased cd's, so burnt cds, etc... i had many problems with the flip down face shorting out and not wanting to sit flat as well.
as of right now i have a 5442 where the flip down face siezed up, and wont work. 3rd time the same unit has gone back to the shop. frankly there are better units out there. with better features, for less money.
