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.
 
The only thing I've found so far is the Resler Interface (USB) that works with Android head-units (along with the i-Bus app and DSP licence).

Doesn't work with non-Android head units though.
