I have set up the power supply as follows Earth = earth Us = Switch +VE SAFE= Perm +VE Sun symbol=Light switch S Kont= Switch +VE K Bus= ? Tel Mute= phone mute Gala=Violet gala wire The unit comes on but asks for code each time. Tried switching SAFE and Us positions but works without key on this setting and still asks for code when turned off and on. Anyone got anything different? Any ideas? The wires that went into original block for RDS 5000 radio are Thick red=perm +VE Thin red/brown= Switch +VE Thick brown=earth blue/grey=Light switch There is also a thin brown wire, I have no idea what this does. I know its laborious but I thought it was the easiest way of describing my situation. Does anyone know of another live position on back of MFD that isnt mentioned. Does not having the 26 pin connector on make any difference? Thanks
