Universal Fiber Optic Loop Bypass Loop Adapter Compatible with BMW, Mercedes & More

I loved it.. it literally took 10 min. To place on my car... the hardest part was locating my satellite radio console in the trunk... i didn't have to break it, like I saw in videos, this part was ready to go.. worth the price saves tons of time.. 5 stars 4 sure..

I received the dreaded SOS error on my 2007 BMW after which I had no sound for 3 months. After doing some research I learned that it was likely to be the XM radio loop. I purchased the product to bypass it. Unfortunately, during that install I had difficulty locating the amp. However, I used the QR code on the package to locate a chat to have customer service support me with locating it. They sent over labeled pics! I now have sound and was able to save about 1200 bucks! Don’t hesitate to buy this product or lean on customer service for support!

Works as expected, saved so much money! Thank you!

The stereo cutting in/out In my wife’s BMW 330iHas been the source of irritation for the last 2+ years. Our local BMW dealer quoted us $1100 to fix this issue, which I politely declined. Recently I stumbled across this fiber optic loop fix on YouTube and decided to purchase one. Directions were straightforward and very easy, even for someone like myself who HATES chasing electrical gremlins. In our car there was four modules that could be suspect so one by one we pulled the green connector and placed the fiber optics loop into that connection (which affectively bypasses that module from the system) and then checked to see if the stereo was again operating correctly. Went through the entire system and to my dismay the issue still persisted. I remember reading many reviews before I purchased this Fiber optics loop and it was mentioned that the gentleman (Adam) who Manufactures and sells this item Is very willing to help troubleshoot if need be. Matter-of-fact there’s also a small card that accompanies this fiber optic loop with contact information should you have a problem. I contacted Adam and within 20 minutes I received a text message and then a phone call. Honestly can’t even remember the last time I had a vendor contact me willing to help remedy a situation. Adam went through each step with me and while doing so I explained that over the last 24 months I had replaced a couple of the modules with used in an effort to remedy the situation. Adam explained to me that these pieces have to be coded correctly with the same identical software for them to function properly In the system. He advised me to put the old modules back into place and then troubleshoot the system again. Within 10 minutes of doing this found that the TCU module that also handles Bluetooth for the car was defective. I can honestly say in all my years I have never experienced customer service like I received from this gentleman in his company. Definitely owe him a huge debt of gratitude. His product and customer service is second to no one.

This worked perfectly. Mercedes was going to charge $1895.00 to replace the module located behind the glovebox. After an hour of work we had sound. I highly recommend it!!!

The only one that fits. I bought one of the others that comes with a male and female connector, but the connector did not fit my BMW (e64). This loop fit perfectly.I was able to determine that the XM module was not functioning and was the “burned out bulb in the line of Christmas tree lights”. Because of the faulty XM module, the amplifier was not working. There were no sounds from anything, not even the back up sensor. I disconnected the fiber optic cable from the XM module and plugged in this loop, thus bypassing the XM module and everything else came back to life. I will keep the loop in place until I replace the XM tuner.

If your reading this you have done extensive research on how to get your audio system going in your bmw. I have a 2008 BMW 750li. The satellite unit when bad causing the whole "I" drive system to go down. The system operates via fiber optic cable. this loop bypasses the bad unit thereby give you audio again.The loop takes 10 seconds to install but to get to that point takes 10 mins. You must pry the inside trunk panel on the driver side to expose the satellite unit. have a small zip tie ready to secure the loop in place to the original fiber loop.While your in there take a pic of the Bluetooth module if your car is equipped with one. you will need that to pair your phone to the car. This unite works!!

Took 10 minutes to remove connector, insert the loop and wrap the zip tie! Phone SOS error gone and my phone connects again!! Worth buying a quality product even if it’s a bit more expensive!!
