Hey guys i really need some help with this its driving me insane! I put my Alpine deck in my new VZ from my old VX last week, i used a new wiring harness bought online and chopped the wires from the deck and re-joined them all, everything works awesome on the head unit but when i turn the ignition off and back on again the deck doesnt remember the settings i had put in or the time etc. I know this is a constant power issue so i got a multimeter and tested the red and black pins on the alpine cable which i perceived to be constant power. it pulls 12V DC which is exactly what it should but the deck doesnt seem to remember any of the settings! Help me please!
