I just got a 2006 330i the radio doesn’t work or the heads up display. Checked all the fuses all were good. Next I checked the optical cable no red light. So I followed all the lines to trunk bought the jumpers and still nothing. So bought the feirton radio that is supposed to be the upgrade touchscreen all that jazz. Then come to find out I have logic 7 so I had to buy the decoder. I plugged it all up there is a clip for it that plugs into something 3 wires but there is nothing in dash to plug it I did research and it’s battery yellow wire black which is ground and red which is acc according to website. So I went to look at harness in car and now trying to figure out while colors are the ones I need I see brown red green stripe and others does anyone have a idea please help it surnames on just no sound out off speakers thanks or help.

No factory Heads up display offered in the e90 series. At least in the US

Those adapters need power there should have been a diagram that came with it .

This is beyond the range of the e90 cars covered here.
As far as I know there was no factory Heads up Display in the
E90's when they ended in 2013
