I went through a similar process trying to figure out how to upgrade the sound system in my 03 EX 4cyl (does not have duel zone climate controls.) Keeping the OEM head unit is too much of a quality compromise so I finally broke down and had an after-market deck (MP3 capable) installed in the CD holder tray down below. It looks the same as the kit pictured above. Anyway, it looks great. I was very pleasantly surprised with the results. The OEM deck is still powered so it holds 6 CD's and the clock still functions but the outputs are disconnected. The only regret I have is the loss of the steering wheel controls but there is a kit that works with the infrared remote of after-market head units that will regain that functionality if desired.

I also had the stock speakers replaced and powered their replacements with a 4 channel amp. A Infinity self powered sub in the trunk gives the low end a little boost. Now the car sounds right.

If you want to do the sound system right, I personally believe that the stock head unit should not be used. It is a poor base to build from. Besides being a cheep hunk of crap, it does not have enough power. So you need an amp, but the head unit doesn’t have pre-outs…. On and on, compromises, expense and less than optimal results.
