I have a 2006 bmw 330i. We bought an android touchscreen head unit and it we'll come on but no sound. We bought a decoder also. But do we need an interface? Are they the same thing? The car has the logic 7 system. What can we do to make the sound work? Help please. [IMG][/IMG]

It's my understanding that the analog to most converter must
be plugged into the FR and Fl of the new head unit
then the most bus connector that
was formerly plugged into the back of the Factory Head Unit.
I have never done one of these it's just linear logic.
Does the converter also require power and does the amp still power
up would be the next question that has to be answered .
You probably either need to put Most Bus jumpers in the TCU
Fiberoptic line and remove the TCU and program the Kombi module
to ignore the SOS signal to .

I am currentley having the same issue on my 2007 335i with logic 7.

Factory headunit works.
Then I connect the aftermarket android headunit through the MOST fiber optic adapter and that woks and there is sound for a few hours. After I turn the car on a few hours later I am back to no sound.

I have done this cycle about 5 times, so its consistent.

Any help would be appreciated.

I got it to work!!! Took me 2 radios and 2 interface boxes but I got it!!! Ended up buying a Eonon head unit and a AVIN interface! Picture of the finished product!!! Yes this is a BMW with logic 7. Now I need to get the water to stop leaking under the dash on the passenger side when going through car wash! Any ideas?
