you have to be missing a wire for it not to fully power up...
make sure your twilight and all lamps are off
and directly connect the unit to your OE plug
see if it lights up
as long as you keep the dimmer off youll be okay |
Do you know if this is also available for this part number unit 25755259?
I am willing to bet all my savings the wiring was fine and no wire is missing. My unit (and all the non-NAV units) have an second ground on F5. On the NAV unit that is a “Antenna select band 2 signal” (thus here is a possible problem – output shorted to ground).
E1 is not needed (is the power antenna, definitely not important)
E4 – not used (in NAV units)
E5 is just a shield
E6 – data wire (essential and was connected)
E7 – Auxiliary video low signal (not important, can go without)
E8 – Auxiliary video low high (not important, can go without)
E9 – Auxiliary audio Left (not important)
E10 – Auxiliary audio Right (not important)
E11 is just a shield
E12 – Audio out left + (not important)
E13 – Audio out left – (not important)
E14 shield
E15 shield
E16 – GND (absolutely essential and was connected)
F1 – PWR + (absolutely essential and was connected)
F2 – VSS (not essential)
F3 – Not used (in NAV units)
F4 – Antenna select band 1 signal (not needed)
F5 – Antenna select band 2 signal (not needed)
F6 – data wire (essential and was connected)
F11 – Shield (for chime)
F12 – Chime signal - (Not essential)
F13 – Chime signal + (Not essential)
F14 – Audio out right - (not important)
F15 – Audio out right + (not important)
F16 – Auxiliary Detection signal (not important)
So there is really no wire needed, all you need is power and data.
