Fiber Optic Lollipop Tester – https://amzn.to/3menBva

Hey guys, todays video is some old footage from last year that I put together. In this episode I show how to test the MMI system and find the problem. 99% of the time, it is due to a receiver in the back of the car that is not completing the fiber optic loop. When there is a break in this loop, it will shut the whole system down causing the screen to turn off. This was a very cheap repair!

To find the cause of the issue, order the fiber optic lollipop connector and then disconnect the fiber optic connector on the back of each receiver. Once you find the problem, the screen will power on. You can leave the lollipop installed for temporary fix while waiting for your used part ordered from Ebay. Your screen will remain powered on once the fiber optic loop is complete.

I’ve seen videos where the loop is used indefinitely. Will that work or do you have to replace the part?
