If you have a factory DSP sound system, you'll need a way to communicate with the DSP amp and tell it to power up. Common issue when fitting a new headunit to a BMW car with DSP.
There are dozens of threads on this site about doing that. A popular option is the Resler iBus adapter and iBus software (applicable to android headunits only).
