I have this connected to the KDC-6025 and it is great! It is a little slow loading songs and If you want to find 1 song out of the 3000 that are on your ipod your best bet is to do it directly on the pod. That being said this is a great product for Kenwood head unit!!!
This is sort of difficult to use but worth it. it gives you control over your ipod, which is great. It also charges the ipod and improves the sound quality
Bought this and thought I would have a good time listening to my new 80 gig ipod and the kenwood adapter; turns out I was wrong, as the adapter doesn't let me do ANYTHING but resume! It resumes when there isn't a song picked! I gave up and used my old ipod (15gig) and it works. Sounds wise, it can not compare to the Music Keg, which IMO is a better product, but more expensive (and hard to find now). Kenwood dropped the ball on this one!
