Especiallythe terminals A7 (ignition plus) and A4(steady plus) are often interchanged.The incorrect connection in this caseleads to following problem: the unitcan not be turned on if the ignition isoff and all the saved settings are lostas soon as the unit will be turned off. Ifthese problems appear the connectionsA4 and A7 should be interchanged.Socket B (loud speakers)On the B side you can find the speakersterminals.B1 – (+) rear right (violet)B2 – (-) rear right (violet/black)B3 – (+) front right (gray)B4 – (-) front right (gray/black)B5 – (+) front left (white)B6 – (-) front left (white/black)B7 – (+) rear left (green)B8 – (-) rear left (green/black)The terminals are coloured by pairs, ineach case one (+) and one (-).2 1 2 14 3 4 36 5 6 58 7 8 7ABThough the design of ISO plug isstandardized, it's pin assigment is notand may vary. Thus in case of mis-match of connections due to differentpin assignments a simple plug'n'playconnection may lead to grievous errors.!
