Sorry Guys,
I have read through several posts regarding the Iphone, but couldn't find anyone with similar problems. The issue is this:

I have a 1st Gen Jailbroke Iphone for (T-Mobile) I can get my Scion to recognize the Iphone and even can control it., but it will not play the music through the car speakers it only comes out of the Iphone Speakers. Any suggestions? Do you need to buy a Different adapter? Any help would be great thanks

Sorry I just realized I accidentally posted in the TC section is there a Way for someone to move this to Thhe Scion ICE Section

 

If I were you, I'd just remove the "XB" from the title of this thread, since all the Scions use the same stock NAV system.
Then I'd post the message in the XB forum as well... just to get more views, which should increase your chances of getting help... and also potentially helping others.
