Doh! That's what happens when I make a quick post after 4 a.m.! What I was actually implying (instead of actually typing) is that those are both single DIN units as opposed to the double single DIN setups historically available from both Nak and Eclipse. Just mentioned that since a '93 has enough space for a twin single setup. At this point might as well mention the fact that Blaupunkt produces a single DIN changer unit for use with a separate single DIN unit.
The big question here is 'Does the question referring to a "cd changer/head unit" only inquire about head units with changers built-in or will info regarding quality head units/separate changers satisfy as well?'...
And let's not forget that anyone who has the space can run after a Ford in-dash changer as well.
One other question for red93coupe -- Have you considered grabbing a few CDRW's and a MP3/WMA capable head unit to act as your "custom changer" while the cost to eventually toss in a HD based head unit/external HD quickly drops?
To top that off, what's the overall purpose for the system, i.e. "just hear some music" or are you looking to go hardcore with the whole setup?
