The head unit

After some help please,

Audi A3 2006 Non Bose, Sub in boot

Bought a pioneer headunit and just bought the full canbus adaptor system for it to plug in to plugged it all in and left with 2 spare wires and not turning on. Any ideas?

Added note I have had to plug the canbus system into the wires provided with the headunit to make it fit. Once of which was 4 coloured wires with system controls and the other wS one wire an plug for mute

Looking at your pictures there are many potential wiring issues, be thank full it never switched on as you could have damaged the unit. Either look at the pinout between the two head units or take it two an auto electrician, as that is not a plug & play wiring harness for an Audi.

Found out its the actual canbus box that kept blowing the fuse on the wiring route. Took it back to the supplier this afternoon
