my subzero head unit is fitted but will not hold on to memory setting when engine turned off!
any help please!
also what is the wiring spare with a blue plug on it?
Well if you take the head unit out again, you should see a red wire and a yellow wire (they're usually standard those colours), and you should be able to connect them different ways, playing about with this should solve the problem, your instruction manual should be even more specific, and explain it better than I can!! lol
Get a radio harness onto it. Those don't go into my radio, I have a harness connecting into those two plugs on that thread, and THEN it goes into the Radio. On that harness, you can switch both wires over... (red/yellow, yellow/red)
