If it’s anE39 5 series I can’t see a radio wire causing a non start, it’s more likely it’s blown a fuse somewhere?

Does the engine turn over when he tries to start it? Do the dashboard lights come on as usual?

Obvious question - can’t they figure out where the wire goes? That’s the first thing to do.

That’s the cause of the problem, most likely, so nothing else matters at this point.

His friend here, the dash turns on, it doesn’t turn over or even click. The radio I have is the android replacement from [amaseaudio.com](http://amaseaudio.com) also the radio doesn’t turn on or even attempt to. It flickered a few times as it went out and it’s Ben dead since

Time to remove the new radio, see if you can find the socket for the loose wire, and put back in the old radio to eliminate the radio as a possible cause of the problem.

Chinese low budget garbage, what do you want for $289. Probably be lucky if some permanent hasn’t been done. Check and re-check your installation and check all your fuses.

What were you doing with the wiring when the problem occurred? Did the car ever start after installation of the aftermarket stereo? My guess is you accidentally shorted out something.

If the car was running fine with the new stereo, then stopped running months later, then the loose wire was just noticed, I think it’s a red herring and nothing to do with the problem.

A loose/disconnected battery wire is usually pretty obvious where it goes.
