The thing I don't like about is that it doesnt have a port for USB access. That is why I love my Pioneer 6000 HU. It can be adapted to the iPod, but I just use the USB function only. I have a 16gb thumb drive I can hook up to it and have the same controls as the iPod has. And at a fraction of the cost.
The Pioneer Premier line is even better. Had I of known more about them back when I got this HU, I would have gotten one of those, but yet I am still happy with my purchase.
