I have replaced my HU with a new pioneer. They provided me with a CP2-UNI module for the steering wheel control but it doesnt work and there is no sound. I have been told its because I have ther Carver system with the Amp in the boot and the subs. I need a K-Bus to trigger the amp which doesnt come from the module Can I get something that turns the standard remote Amp output from the HU into something the car can recognise. Otherwise I am being told to replace the Amp with an aftermarket one. Any help would be much appreciated.
