So on my 07 cls550 the nav cant find my locstion keyless go doesnt work and my ipod connect wont work either. I bought the car like this when I took it to Mercedes I waited for hours and they said they were having problems diagnosing the problem after they kept it over night they said it was my audio gateway unit but after some research it sounds more like the central gateway unit to me.anyone have any advice on the subject?

 

I forgot to mention the voice control lever on my steering wheel also doesnt work it currently has no function at all

 

Please post your questions on the CLS forum. The CL has very little in common with the CLS.
