My wife just bought a used 2010 C300 with 10K miles. First Mercedes, first German car owned. Our other ride is a 2001 C5 Vette. Can anyone tell me how to activate the AUX jack located in the glove box? My manual says push the DISC button twice but that doesn't do anything. We have an extensive library of DOOWOPS on and MP3 player and want to listen to them on our next road trip. Any help or guidance will be appreciated. I've been am member of the corvetteforum.com for several years and it has been a life saver for me and I'm hoping this forum will do likewise.

 

Manual says, Press button DISC repeatedly until the main menu for AUX operation appears.

> In CD mode: Select CD/MP3 -->Aux.
