This is my first post but I promise I did plenty of searching to try and find my answer so if I missed it go easy on me.

I just got a 2010 GS with the Non-ML sound system. My iPhone 4S paired up right away and streams audio BUT it sounds like it is getting louder and quieter while its playing. This is the first sound system I've had with BT audio so is this just something I have to deal with or is this something I can change?

Any help would be great!

 

If you are accidentally hitting the volume keys on the side of your phone, it will change the wireless volume at which it will play on the car speakers.

Check to see if you have ASL enabled in your sound settings. ASL is the auto sound leveling feature that raises and lowers volume based on speed/ambient noise. Good luck!

 

It was the ASL. Thanks a lot for the help!
