First I want to mention that the radio has been ordered in the morning at extreme audio and already dispatched at noon. Two days later it arrived with me. There's nothing faster, just perfect! For Radio everything has already been said, so I can save myself a repeat. Only the operation I would like to describe my impressions: If're upgrading from a VW radio on this device, you will be struck by functional overkill! The radio is a printed Quick Start Guide and in "detailed" Instructions on CD. In addition, reference is made to a guide on the homepage of Kenwood - not really help!
Maybe I even get used to the operation of the device. If not, then I'm going just ran always right to change the radio station ;-(
Conclusion:
Functionality: incredible (in my opinion way too much)
