My clock stopped working after I installed my sony cdx- gt350mp into my car. My won't save my settings and I have all the correct wires connected only lose wires are for my remaining two speakers that aren't hook up.
If it is working but isn't saving your settings then you don't have the wires correctly. Check your main power (constant) wire. It is the yellow going into the head unit. That is the one that keeps constant power so the settings are saved.
i checked the wire and I have all four wires connected to each other two yellows and two reds all connected so the radio can work. tried jus red to red and yellow to yellow but the radio doesnt turn on.
