Kenwood KMM BT325U Not Working in ’06 BMW 325i

Last month I installed a KMM BT325U in my car. It turns itself off and on intermittently. Blue Tooth sends it into complete chaos, it just cycles off and on. When it works, it works flawlessly. It just isn't very often.

I read there may be issues with the stock amplifier, but I can't find that info anymore. I installed it myself with a Schoshe kit. Wires are soldered.

I bought the unit from Best Buy. They said it was the Demo Mode. I told them thanks, but no. Any ideas?

Thanks in advance!

So I figured out my problem   The red wire in the adapter didn't have any juice. Turns out for this adapter it is just a dead terminal. So I put the tester on the orange wire. It was hot, so I hooked it up and I dealt with the stereo turning itself off and on as it pleased.

This morning I went out to start the car and get the heater going a little bit, so I turned the lights from "auto" to off and the stereo turned off. I switched the lights from off to auto and the stereo turned on. In short, I hooked the switched power wire to the friggin headlights. My headlights are always on "auto" and they turn off and on as I drive, so....

I need to run a wire and fuse to the fuse block or hook the switched wire to the constant and hook up a switch.

Hope this helps someone down the line.
