Can anybody help please cracking up here and the radio out loads and back in. Bought a aux cable with the 3 wires red white yellow installed it in the back off the radio set up the aux option in vcds and all good. Plugged in alexa auto and sound its good but there is still a constant hissing/buzzing in the back ground. The buzzing almost changes as i accelerate also. Spoke to someone earlier and suggested i move the earth cable on the aux cable but still no luck.
