2005 S500. Installed a new MB bluetooth for the phone system, all works fine including the contact list with my Android smart phone. Now I want to stream Pandora and no one knows how or what I need, other than ripping out the whole system. There is no connector in the glove box. Is there a harness that I can get to plug into the back of the car stereo, or another bluetooth option?

 

I understand why people say replace it, you can throw only so much adapters to the factory before you have to realize that it is so outdated that no amount of expensive band-aids are going to help.

However, Mobridge combo will work in your scenario. done a few of these in the past with great results
