Stereo Woes

Ah this may be the same thing then. albeit mines a 54 plate.

Sony XAV-AX3250 is the latest one im trying to get working.

Thanks,

The 20 pin connector on the back of the head unit doesn't seem to follow a standard, at least different manufacturer's use a different pin out. The cable assembly that goes to the DIN plug is meant to be standard at the DIN plug, but my Jimny was wired incorrectly on the DIN plug.

Either the 'Light Control' (Dimmer) or the ACC+ was in the wrong place.

ACC+ would stop the whole head unit from turning on, the light control would just stop the unit from dimming.

If the head unit powers up but no audio then it suggests either the speakers are in the wrong place (unlikely) or the unit is muted. The only thing I can think of that would mute the Sony is the 'reverse in'.

I found a wiring diagram for the Sony, but it doesn't show pin numbers on the DIN connector, just colours.  I can't seem to find the Jimny wiring just at the moment.

Thanks Robin. I'll take another look today.

I think the most confusing thing here for me is having 1 working Sony HU and one not. I have checked the harnesses to see if there's a difference or crossover but there isn't.

Do you think it's worth buying a new ISO adaptor and of so is there one anyone recommends?

So found this elsewhere on the forum. Anyone know the accuracy and if so, what I need to do here?

Scrap that, its for Gen4. Doesnt match.

How desperate are you? Can you wait till tomorrow morning when I can take my Sony out of my 2018 and compare?
