This harness is nice and it is convenient, however, if you have a stock amp in your system this harness doesnt wire it correctly. You have to connect the antenna wire on this harness to the amp wire on the cd player.

Installed in a 2001 E46 BMW 325i.

Easy to solder and distinguish the correct colours. Wires come pre-cut avoiding the hassle of de-shielding them yourself. Highly recommended.

Works great! nothing like begin able to just wire the radio to the adapter and plug it right into he car! If you are doing a BMW make sure you buy he antenna adapter.

Definitely a must have piece when putting a non OEM radio in a BMW, or any other car for that matter.

Makes the installation job much easier and faster to complete.

This item made easier the installation in my car, just plug and play.

Works great in my BMW 330Ci. I recommend.

Vehicle: 2002 BMW 330i
Works OK stock but a bit bulky. I had to get key-hold saw to remove a rear plastic brace to get my new stereo (Pioeneer DEH-P5200HD) to fit. Also, if you're going to enable your steering wheel controls by adding the Axxess ASWC (which works great by the way) then you'll need to relocate the orange pin. It designated for illumination brightness control but most radios will ignore it. Instead you need to move the pin to an adjacent hole in order to pick up the steering wheel control signals (see the pinout in Axxess ASWC instruction sheet). I used pliers to yank the pin out and then put it back in the right hole.

This item works perfectly and fits nicely on the integration of my BMW 528i and on the JVC head unit.

Great product and fast shipping.

Made installation easy!

I would highly recommend business with Sonic. I have purchased many products from Sonic and have been very pleased with everything from the ordering process, shipping time, and quality of products.

I've been using product for about 6 months now and it's worked flawlessly, I got it at a good price and shipping was quick and price was reasonable. Thanks
