I'm keeping my original head unit, because it's a dual CD/MD slot loader. It's useful for when you go for a drive with your mates, and one of them has an MD or CD they would like to hear on the big system.. (Especially as one of my mates has a little studio, and uses MD to test the mix =)
As to a CD holding only an hour, that's when you press the aux button and crank up the empeg..
Best of both worlds.. =)
