I was came across this site a few day ago and found it one of the more informative forums about our beloved 6.
I love the car but my main complaint the whole time was the integrated cd player into the dash. I was sitting around
thinking about ways to spend my money when I got back from Iraq and I found a nice dash kit for the Mazda 6 though
it costs a little on the high side. Here's the link, though you might find it cheaper somewhere else though.
