I recently wrote how I replaced my factory head unit in my car with an aftermarket one. One of the problems I’ve been experiencing however, was intermittent sound AND no radio. I had a weird issue where the head unit also wasn’t powering up too. The speakers were dropping in and out, and also the next time I fitted the aerial wire, the head unit would no longer power up.
Needless to say this confused me, until I did a bit of investigation
Turns out that the ISO adapter harness I purchased to fit the head unit to my car, was connected to the block. However there was always a little bit of “play” where you could wiggle the connector in and out 2-3mm which I was never happy with
This small amount of “play” was enough to break the connection between the pins and cause a signal loss, and power loss. Hence why my previous testing on the head unit wasn’t showing any problems and why it randomly powered up again after I tested it
Basically I added two zip ties tightly against the harness, one near the speaker wires, and one near the power. It’s now permanently solid and worked flawlessly sinceViews – 195
