I haven't had a "system" in over twenty years, and was REALLY enjoying finally having this for the three days it lasted. I'm bummed. I pulled up to a stop-light and it just quit. I didn't smell anything that resembles "electrical smoke", but the display went dark and it wouldn't turn on again. I did have the volume about 93% of the way up . . .
I thought I blew a fuse, but checked all three (including the one in the Head Unit itself) and they're all good. I even checked them with a continuity meter just in case. Then I went a step further and made sure voltages were getting to the harness where it plugs into the back of the HU. All good. Constant, keyed and I even double-checked the ground and they're all golden to the point where the harness plugs into the HU, so it's not the wiring (which is all soldered and heat-shrinked into a factory harness connector/adapter).
My question is regarding the probability that I got a lemon, or if I abused it by cranking the volume? I just want to make sure this doesn't happen again when the replacement comes. I've never blown anything before in my life, and I always make sure I keep the levels below any audible distortion, so as not to clip the outputs. I had it loud, but it was still sounding clean.
When I removed the HU, I smelled it real hard, but nothing smells burnt at all, so it's weird. I would think that if I blew its internal amplifier, I'd smell "electrical smoke" and it might still turn on, just wouldn't output any signal . . . but this thing is as dead as it gets.
So should I take a chance on another one? Is Blaupunkt an unreliable brand? Is it likely I just got a defective unit, or did I cause its death somehow?
I just ran all the wires cleanly hidden, including the external microphone for the bluetooth calling. I don't want to go through soldering another 18 wires or so for a different head unit, if I don't have to.
