How about 'Empeg Digital ICE'? (stylized empeg logo, of course)

I read the previous post advising against acronyms, but think about it. The standard display is blue, and blue is suggestive of ice -> cool; with the double meaning of 'In Car Entertainment'. Those 'in the know' would recognize it as an acronym, and those who aren't would (i presume) think something like 'cool'. The way the display glow diffuses reminds me of light shining through ice. It really doesn't really matter if it's red, green or blue, it still has the 'illuminated ice'-y look to it. That text line shows the manufacturer, and is vague enough to cover the mp3 (and future wav) capability. The 'Digital ICE' thing has something to work with as far as 'catchy' goes (maybe?). 'An ICEbox of cool tunage'.
