Mr Mac I have the Alpine IDA-X100 ipod head unit, I have been through a fair few in the past and this is by far the best I ever had. There is a new version out now which adds even more features like built in bluetooth I believe but dont hold me to that, its one of the only properly licensed ipod units, meaning it has the full official ipod interface and shows all album arts on the display. It does not however have any CD input so its ipod or radio. I go for the overall sound of my music than just volume and this unit delivers in spades! It has so many adjusments unless your a qualified sound tech you may not be able to get the best out of it lol
I have changed mine to red and it looks like it came installed as OEM. It also hooks up with the steering wheel controls which cost me about £25.
