Tune2Air Issue

I bought my Tune2Air bluetooth adaptor a couple of months ago and it was working fine until this week. The device is powered and shows the blue LED light. It is paired with my I Phone but I can't get it to play any music. If I select the media interface from Command, it just says to music files available or something to that effect. If I turn the car off so there is no connection my I Phone will play music through its speakers but as soon as I turn on the car (and presumably the bluetooth connects), the sound of the music I am playing goes silent on the I Phone even though the track is still playing.

Any suggestions as to how to troubleshoot this?

With the Tune2Air powered on, disconnect the Tune2Air from the Ipod cable, wait a sec and then reconnect it. Turn off Bluetooth on the Iphone and then turn it on again. If that fails, click on the device in the Iphone list of available devices, select "Forget This Device" and then re-pair the phone to the Tune2Air.

I thought with the bluetooth paired you have to select "AUX" under the audio options.

Possibly 07-09. 2010 got a dedicated IPod input cable and a "Media Interface" source on COMAND.

Thanks for this, your instructions worked

Only thing now is that sometimes with Pandora, the song and artist show up on the dash but usually after the first song, the display does not show any future songs that are played. It seems to stay frozen on the first song that is played after start up

Yeah, that's more a universal issue with Media Interface. Even with a direct connection to an IPhone and even playing local files via the Apple music player (the most optimal set up as far as the tags are concerned) it still lags or freezes the artist/title. If you want to see an MB system that actually works with Pandora, get a GLK as a loaner next time the S is in the shop. Or a prior gen C or an E. Pretty much any other car MB has made in the past 5 years.
