BMW NO Audio/Radio FIX! A Very Simple $10 Part

My 2007 BMW 335i radio stopped working so here is a very simple fix to get it working again by only spending $10. This optical loop bypass is very easy to install. It originally didn't fit on my car so I had to modify it by cutting off the housing to expose the two plugs.
Amazon states that it fits on all German cars.. BMW, Audi, Porsche, VW, etc.. but that's a total lie. But you can still make it work. The
module is located in the trunk underneath the carpet. Just lift it up and you'll see it. Remove the plug going to the module and attach
this piece. That's all there is to it! Very simple fix. If you need help, please leave me a comment and I'll see what I can do.

Maaaan what a coincidence. I had that Sweet Leaf stuck in my head the past two days and that’s the song that comes on when you get the radio to work again!

[@Atlantismonkey40]

What a strange fix. I’m not a car guy. That was very interesting. About ten years ago the engine light came on my truck. Went to the dealership to see what was the issue. I had a small child at the time, didn’t need a breakdown with her in the car. 4 hours later, the dealership technician informed me the issue can be fixed in two days, $1,576 US dollars. To me: the money was not a big issue, the safety of my child and passengers were the issue. Not to mention a two day car rental. On my way home, stopped for gas. An employee at the dealership came up to me and said. (I had seen her at the the dealership). She said the fix was very simple. She walked me thru the process. It was a pug and play part. Went to auto part store. The part was $65 dollars and I was able to fix in 20 minutes. Sometimes dealership are as croaked as they come. By the way the girl at the dealership. I married her two kids later. I’m still not allowed to take car to dealerships. Haha, I guess it worked out in the end.

Did you bypass the module or the amp , Mechanic tells me I need the Amp and needs to be programmed $1400 is that right

[@OakInch]

@@luiscosta19123456 I took the module out of the circuit with the bypass. I bought the part in his description that required no modification. I'd try this first before forking over 1400. The part is cheap.

I’m having the same issue and I believe I have pinpointed it to a bad amplifier which I believe is what that optical wire gets connected to. What I’m wondering is what the repercussions are for not having it connected?

[@keysersoze8453]

Great video! Did a great job being concise and solving the problem! My only criticism is why take the time to make this video and help people and not simply SAY WHAT THE PART IS CALLED?? Everyone has to go search thru comments and find your reply which took longer than watching the video.

[@audioalarmtechusa]

???wow Many senior automotive mostly uses in media oriented systems transport system, and because the system module is the series connection in the maintenance process when a failure occurs from a module of the media oriented systems transport, it may cause the whole system does not work, in this case, you can replace the module in series connection in the loop to determine and confirm working condition. Usage: If you meet the faults of audio CD and navigation systems, audio CDs don't work, navigation is often broken and always blank screen, it may be caused damage to the telephone module. The modules connected on a vehicle media oriented systems transport ring include: CD Changer, Video Display, GPS Navigation, Mobile Phone, Bluetooth, Voice Recognition, Amplifier and Digital/FM/AM Tuner. If you wish to remove one of these modules from the fiber optic ring for repair or fault diagnosis you will require this connector/adaptor and fiber optic bypass loop cable to close the media oriented systems transport ring and maintain the integrity of the remaining modules on the ring. Specification: Material: Plastic, Metal Fiber Optic Loop Cable Bypass Connector Length: 900mm / 35.43"(L) Dimension: 940x27x13mm / 37.01"x1.06"x0.51"(L*W*H) Color: Orange, Black, Blue Pin Number: 2 Connector Size 1: 27x25mm / 1.06"x0.98"(L*W) Connector Size 2: 35x25mm / 1.38"x0.98"(L*W) Compatibility: Fits most kinds of cars. Note: Color might be slightly different due to the color calibration of each individual monitor. Please allow 1cm to 5cm measuring deviation due to manual measurement. Item Includes: 1 x Fiber Optic Loop Cable Bypass Connector

so your amp failed which means you’re bypassing it. check all speakers some may not be getting power. as well you could end up overloading the bridge and burning it out sooner than later

You have a faulty Nav module...All you did was bypass it with the Fiber Optic test tool. As that tool is to test which module is bad. As the way BMW work. The fiber Optic line is used to monitor the system to all the modules. If a modules goes bad anywhere in the system You will lose the function of everything past that fault... You start at the one in the Glove Box. Then work you way back....
