My radio doesnt effect the display one bit at all ????? There is 2 wires left in the standard power ISO block which are not connected to anything in my radio, a orange lead and another which i cant tell (colour blind and way inside the dash to see!!!)
surely though, in the third ISO jobbie there must be one power lead that comes from the light switch to the standard radio and then back out of the radio through another pin on the third ISO plug and off the the steering wheel controls? so if that is true then im sure a circuit can be made in the third plug, just need to know which wires are which !!!
