Newbie- need words of wisdom

[kmpiotrowski]

Hello 1addicts,
Yesterday I bought a 2012 135i vert w/o iDrive and I am still figuring things out.
I have an iPhone 5s that I have Bluetooth paired and it works great. With it plugged into the USB, I can also play the music on my phone through the car speakers.

I would like to be able to use my phone for navigation, and have the turn by turn come through the speakers. Do I need to do anything special to do this? I see all this talk about Y adapters (don't think I need this) and Snap-In Adapters.
With my Subaru WRX, I just switch the audio source to my phone and just use Waze. My stored music will play and when Waze wants to tell me something, it lowers the music and the turn by turn would come through. is this how the 135i works?
Your insight is appreciated!

If you use the AUX input any audio that is played on your phone will go through the cars speakers, but of course you won't be able to control your music with the steering wheel controls. Otherwise you have no choice but the Y-Cable
