JY-UOS01N4 no sound with BMW E87 2004

[vschelle]

Hi,

received my head unit today and I immediately installed it.
I’m using the CTSBM009.2 connector with the universal patch lead.

The problem is that I have no sound. When I plug in the old radio I get sound immediately. It is not muted or anything and I think I have wired everything correctly.
There is not much you can do wrong with the CTSBM009.2 I think.
I haven't connected the KEY1, KEY2 and GRND(don't even have a ground from the back of the unit!?) yet from the patch lead but I don't think that is the issue?

Please help. I’m loving the unit for the rest!


Greetings,

Vincent

No help?
I have switched the harness to the CTSBM012.2 because this one has amplifier support, but still no sound!

If I even disconnect the fiber amplfier from the car and connect the default radio I have sound, so it's not even needed to specifically connect the amplifier.
I have a youtube video of how everything is connected: https://www.youtube.com/watch?v=9sVo6kg2thA

Currently I have spendid over 600 euro's ( with the additional ) harness to get this to work. Very disappointed with the product so far.

Please help or advise

Managed to fix it. Found a blue wire that was not connected in the ISO connector. Connected that to the AMP-CONT and voila!
