Yes an Android will eliminate the radio unit by the battery. The only way to test the units that I know of (without being an EE) is to install in a similarly equipped X5. If the problem lies with your radio unit then the replacement head unit will fix it. If it lies with your amp then you will need a new amp.

A lot of wires indeed. The twisted pair wires are the ones that go to the speakers. You could test for +12v constant and +12v on the remote wire when the radio is on. I think you said you are getting 12v constant already but if the radio isn't sending the remote turn on signal then the amp won't power up. You could check ground continuity as well, but I doubt that's the problem.
