82110149391 -BMW Auxiliary audio Input for 3 Series with navigation

Amazing product. Genuine BMW product. I got this for my 2004 BMW X5 4.4i with navigation system and this plugged and played perfectly. I got tired of a FM transmitter because it was static and foubd this was a great way to add to my car. Installing it in the glove box was difficult because drilling holes and taking it out was hard, but the set up itself was easy. Only took an hour of work because the glove box was difficult. Could easily be only a 30 minute installation. Don't waste money to get it done at a dealership

Just wanted to post a general warning: for this kit to fit an X3 harness, the cable in this kit has to be disassembled and the pins have to be trimmed. You will need something to use as a pin extractor to push the pins out of the black housing so they can be trimmed and inserted into the existing pin locations on the back of your radio. The pins on the red/white, blue/white, and brown/white wires are too long and will not fit the X3 harness as-is. Once the long metal points have been trimmed off (don't cut the entire pin, just the pointed end), you can insert the cables into pins 3, 4, and 10 (respectively) of the small black clip on the harness where it connects into the back of your radio. Otherwise, works as expected!

This OEM cable was a breeze to install on my '04 330xi with navigation. Pulled the screen out and the wire just connected right into the existing plug on the harness. Mounted my jack under the window controls next to the shifter for easy access. Piece of cake install and now I have better audio connection options using my phone. Only disadvantage is the volume is the only steering control that works. Skipping songs or stations doesn't work but that was to be expected. It also works great if you use the navigation from your phone or get a phone call because all the audio goes through the car speakers.

It just works. The instructions that come with it aren't that great though - for example, they reference other documents that aren't included. I highly recommend browsing YouTube -- endless video instructions are available there. It's a lot easier to install this if you can see what you need to do. You'll also need some tools that aren't standard. Off the top of my head, you'll need a plastic car trim remover and a thin metal "key" tool to remove the GPS display. Again, YouTube is your friend. As far as the aux cable itself goes, it seems pretty high quality. The cable is wrapped in what I assume is a protective layer of cloth.

did not fit , also the seller is not cooprative

Due to the uncertainty of my purchase I researched the wire diagrams on bavauto.com All of the auxiliary wires that BMW makes for their vehicles ARE THE SAME except for the connector pieces and pins. If you look at the diagrams the resistors are about 300kΩ which triggers the headunit to register an available auxiliary mode. This is available on ALL OEM aux cords. I DON'T FEEL LIKE PAYING 80 BUCKS FOR AN AUXILIARY CORD!!! Here's the wiring diagram: (page 14) [...] The connector piece on this was meant for an E46 M3, but I was able to splice new connectors to the cord. The ones that come with this (not the plastic casing, but the actual metal contact connectors <2.54mm pins>) were male. If they were female all I had to do was pull them out of the plastic and put them in the existing one on the headunit. I bought some jumper wires (2.54mm or .1" with female pin connectors) for 3.40ish on amazon as well so that I could connect the wires to the little plastic housing. The pins stick out of the headunit in the zed4 and connect into the wiring harness as opposed to the m3's where there's female pin connectors on the headunit itself. This is a way to save at least 40 bucks by doing some DIY. It will not degrade the performance of your audio if you do it right. You may solder or use butt splicers, whatever you like. I used solder in this case. ***I later found out that I could have just easily made an Auxiliary cord. See this site for details. Full pictures, diagrams, and steps on "how to": [...] Hope this helps some of you!

Earlier, I had installed a DICE kit to connect my iPhone to my 5, however it cause all sorts of problems with battery drain, and ultimately ended up costing me two replacement car batteries. I was despairing for a solution but found this little thing - something BMW should have built the car with in the first place but made it an after-sale option so dealers could charge you for an hour of labor. Installing was time consuming but easy. It took me maybe 4 hours, most of that spend second guessing everything because of lack of confidence :) The other work is guiding wires through somewhat narrow spaces, drilling holes for fitting the jack in the glove box, and just plugging the adapter into the back of the radio unit (easy). All in all a very worthwhile install, and anyone with a modicum of tinkering ability can do it themselves.

Dint take long before the wires started losing continuity. Sitting on the console, I would suddenly lose one side of the car's sound. Touch the cable and it would return. Happened on multiple devices, so it wasn't my iPhone that was at fault.
