Review on Enhance Your Car Audio with Crux SWRAD-55 Radio Replacement Accessories by Rodney Harris

This is not plug and play for c5 allroad. I also had to solder it into the factory wiring, the kanbus is junk. When the machine is half running, there will be a loud clicking sound when the machine is turned off. Steering wheel controls do not work with Pioneer Head navigation unit. Does not have connectors for factory installed plug-in navigation/car phone accessories. I half believe it doesn't even work. The main unit needs to be turned up to high volume to have an adjustable volume level. Really disappointed to look elsewhere or do it yourself.
