E85 / E86 BMW Z4 – Android tablet integration

Hi, I'm new here and I found this great thread about integrating the Junsun V1 Plus Car Radio for BMW X3 E83 2003 into a Z4 E85. I already have everything at home, but now I'm trying to figure out how to connect the high-to-low converter to the cables. Do you have any wiring diagram for where to connect it? I assume the amplified output from the Android radio needs to be reduced so that the original amplifier doesn’t have issues and the sound doesn’t get distorted. I tried it without the high-to-low converter and the sound was also good, but I’m worried the original amplifier might have problems at the final stages.

Hi Ravemare, any progress on this? I'm considering something similar. Did you have the original popup/nav screen?
