Summary: I bought this unit for the iPod integration, and haven't been disappointed. It is very easy to plug in, and sounds great. BUT the user interface is horrible. I have had it installed for six weeks, and still have to pull over (or wait for a traffic light) to switch CDs or iPod playlists.
Summary: I suppose the reviewer before me has had bad experiences with other head units, and while I sympathize, I can't exactly say that this thing is easy to control. Yeah, the heiarchy system does its best to emulate the style of iPod control, but it takes a bit of getting used to.
Summary: I initially was going to buy the similarly-priced SONY competitor unit. But then I started looking closely at the iPod navigation procedure on the SONY, compared to the Alpine, and quickly realized that there was absolutely no contest.
Summary: I wanted to buy a CD reciever (head unit) for a long time and since being a student, I was on a limited budget. I actually zeroed on three units - two of being pioneer ($180 and $160) and the other being the Alpine CDA -9883.
Summary: This is my 3rd Alpine, and I don't think I'd ever buy another brand. The looks, ease of installation and sound quality are all first rate. The iPod interface to me is exceptional, even considering the connector cable isn't cheap.
