Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
What happens is the after market components do not match with the vehicle electronics and on Mercedes almost all electronics communicate with each other.When an after market component is installed this can disable the feature you see that isnt working now because the after market component isnt fully compatible with the vehicle.This is common unfortunately and the choice is to either leave it be as it is or have a factory unit put into it to correct this issue.I have seen this several times before with after market components.
