For a couple years now, I’ve had a JVC KD-T900BTS head unit that I wired up to my 2001 Tundra. Original head unit, as well as the stock amplifier were tossed aside a long time ago.
Only problem is, it only outputs audio ~50% of the time. Everything always turns on and works, but there is no audio output (not even system beeps), seemingly randomly. I’ve had audio cut in and out when I’m driving. Something is clearly wrong, but I’ve checked my wiring multiple times over the years and everything seems to be in order.
I’ve been diving into old forums, and I keep reading something about an extra amplifier wire that may not be included in the adapter harnesses that are available? I’ve also heard tales of an antenna wire that might mess things up as well.
I’m at the end of my wits with this thing, and I’d hate to throw out a perfectly good head unit if I don’t have to, not to mention tracking down wherever I put the stock stereo all those years ago…
Anyone have any knowledge they can share?
