I have always been partial to Kenwood head units... they hooked me in with the original mask stereo (the one that used to spin around and present the world with a blank panel.) That stereo was great, it had CD changer controls and built in equalizers allowing you to pretty much change anything you wanted with regards to which speakers got what frequencies and volumes.
Anyway I just stuck a KIV kenwood in the Coupe. It is mechless (IE has radio in it only, no CD's etc) but it is capable of bluetoothing to the Iphone or controlling an Ipod. I just have all my music on a USB and it read it all off there.
It looks good (suiting the dash I think) and the screen on the right acts much like an Ipod screen... it shows you the artists and then you select the album... it shows album artwork track length etc. The only drawback to it is that unlike with a mechanical system it is pretty hard to change music while driving as you need to look at the display.
