2012 Mercedes-Benz SLS AMG Roadster: Playing Music Through the Aux Jack
May 14, 2013
Our 2012 Mercedes-Benz SLS AMG's audio system accepts digital music files through either a 30-pin iPod jack (iPhone 4 or earlier), or a standard headphone/aux jack. Technology marches on and many of us have been upgraded to iPhone 5 with its new and controversial Lightening connector. Lacking a proper Lightening-to-30-pin adapter, the reliable Aux jack saves the day. This has its advantages and its disadvantages.
I can now use the familiar iPhone interface to select my music (and I'm not forced to decipher another software rationale for alphabetization, etc.)
I don't have to switch screens to control my music
The Aux cord I have is 6-feet long and it will extend to any seat in any car
The Volume control on the steering wheel still works
The "Next" or "Previous" buttons on the steering wheel do not work.
If I'm charging my phone at the same time (so as not to run the battery down while on a long drive), there are now two cords attached to my phone
There was some interference; a very high-pitched sound that grew more noticeable when I was also charging the phone
