Finding a head unit that looks good (i.e. not chav!) is the difficult part. It seems the aftermarket mainly caters to barry boys these days, so good luck in your search. I'm still on the stock radio as I couldn't find anything that offers all the nice features of an upgrade system while looking reasonably "original". Depends on whether you can stand flashing bright blue lights I guess  
  
Keep us posted with your progress - sorry I couldn't be more help, but I'd be interested to see what you choose  
 
  
Guess you haven't looked hard enough then. A lot of the main headunit manufacturers have an RGB colour chooser so that you can set the buttons to the same as the OEM buttons (or any other colour you wish). I'd personally say that's anything but "barry boys," maybe you've just been looking at the wrong end of the market, or just in Halfords or something . Try someone like Kenwood, a lot of the German manufacturers use them as an upgrade from OEM. 
 
 Anything but Ripspeed and you are fine  
  
Maybe, JVC do some hidious headunits
