Kenwood dmx7706S - Absolutely love this thing. If you install it with the Maestro DataLink, the steering wheel functionality works. The one difference is that the volume requires multiple "clicks" up/down, rather than just holding up/down. (Holding down mutes the system, which is actually pretty cool if you have to scream at kids in the backset. lol) I also replaced all four door speakers with Kicker CS but left the sub/tweets. This Kenwood has a lot of depth when it comes to audio configuration. Sounds really damn good now.What head unit did you put in? does it work with volume controls?
