I inherited this '87 325is with the premium sound system about 3 months ago. It's aftermarket Blaupunkt head unit always had power but never made a sound. A few weeks ago it started working fine during my drive home from work but then never came back on again... until yesterday. Of course, this morning it's gone again.
I know it's not the head unit because I bought a new blaupunkt off of amazon. They have the same wiring harness so I was able to just plug it in and again it powered right up but no sound. The connections all look good and the front and rear speakers have different wires so it wouldn't make sense that it keeps coming back all or nothing.
Also, when it works it's always at startup and it works for the duration of that drive. Thanks in advance for any help on this.
