hi guys,
some of you may have followed my post relating to my retrofit hi line sat nav and the problem of no sound...............
well on peeling back the loom i find a red and green wire that has been cut and taped, i donnt know if this is essential.
The car origionally had an ISO fitment to a aftermarket unit.

i am thinking that this could be my issue with sound......any ideas???????!!!!!!

Is the red/green wire on the harness you've installed or part of the harness in you car ?

thinking about it i may be having a senior moment and it may be in the old harnes..........but it was cut so i am wondering if the main harness part is also cut.

o idea what it is as i have not got the wireing diagram yet!

On later cars there's a red green that is left with a cut end. It's the mute for installing a telephone. Unless this is touching earth, it will have no effect.
