Works fine

Easy to splice and follow. Wire colors were clear. Plastic was clean of burrs and fit correctly. No problems with installation.

Works great with the stock wiring

Got this for my '98 BMW 328is with the HK system and stock amp. Works just as described and was a quick install. I just shortened the wires since there was a little too much between this and the head units wires. Been working great for a month now.

Just Works

Does everything it is supposed to do. Fitting it in my 1995 BMW 318ti was not too bad. I found a place to tuck the harness away to the left side of the head unit.

Easy install

The adapter made installation of my new radio a much easier task. It does make it a little more of a challenge to stuff all the wiring back into the cavity area behind the radio on a '98 bimmer. No cutting of the stock wiring is always a good thing if you can avoid it and this adapter is the trick.

Wires in the harness are loose and cause distortion on bumps

The harness fit well to my deck, but the actual wires in the harness are extremely loose, and when i go over a bump, my music cuts off for just a quick moment, i'm attributing it to the loose wires in the harness. They should be quite fixed in the harness and they're not. I would suggest the company to create a more sturdy version

Does the job, if you really need it.

If you might someday reinstall the factory unit back into your BMW then you should use this. Is your particular car so rare, is your new head unit so expensive that you might reinstall the factory unit?

This is a very large connector and is only one half of the connector. It takes up at least two square inches behind your new head unit. Valuable real estate in such a finite area of space.
Am I saying that you might be better off soldering or crimping the wires together? I am, if the first paragraph doesn't apply to your car.
I used it in my car this time and it cost me much time and effort. I will not be using it in my next install though.
