This product works but you have to trim it like I did in the picture....when u buy product it has a square block around the 2 little pieces u need to test components so just trim it with some pliers. It worked so I can bypass my radio to work in a 2009 Mercedes S550. 2 days ago my radio stopped working asked dealership just to look at problem that cost 180 just to see what problem was..... I used this piece to test components and found out my VCM module stop working and that controls radio and voice for navigation so I bypassed it with this piece and radio works now but I still need to buy module which is 1500-2000 from dealership but I found one on Ebay for 300....that saved me 180 for myself to diagnose the problem

Worked amazing was having issues with my radio on my bmw e90 but hooked this up to my blue tooth Module and fixed my problem now my radio works.

Great quality, good price and excellent customer service

The fuse for the CD Changer in ‘05 Merc C55 AMG kept blowing out causing the entire stereo to go out. Pulled out the CD changer and used this bad boy and I’m set for good. No more having to change out the fuse every other week.

Works as it should to bypass any fiber optic component.

Didn't fit my BMW 330i but i cut it a lil and my radio is working perfect. Wish I knew bout this earlier radio wasn't working for months lol

fit perfectly and helped to diagnose the problem in my wifes car.

I don't know how to use
