5 stars for service and product
Junior on 27/11/2014 5 star rating

A week running this unit in my car I thought i'd give it a little review. I don't use cd's at all as my music files are either on a usb stick or on my ipod so this kenwood mechless item was the perfect match for my needs. I changed from the factory stereo and noticed a difference straight away with the extra watts I got from the kenwood 4x50watts. Really easy to use and no problems with delays etc loading my ipod which has a fair amount of gb stored. Thanks to car audio centre for installing this for me and I will see you guys soon to install the inphase subwoofer you showed me.

Excellent unit

    It says "steering wheel controls" so does that mean the volume and tuner up and down function on my steering wheel stalk will still work with this? It didn't say if you had to buy something else?

    hi there yes thats correct, the unit are steering control ready you do have to purchase the correct SWC harness in order for it to connect with your aftermarket stereo.
