5). Press "Music" app on the iPhone
6). Begin to play a song.
7). In the lower right corner of the iPhone screen, you will see a small white box that looks like it has an arrow going through it. Tap the box, and you get two choices appearing on the screen. One says "iPod connector" (I think), the other one says "Car Multimedia". Tap the "Car Multimedia" choice. This apparently forces the iPhone to connect with bluetooth only, leaving the USB port to act simply as a charger. I think after you do this that the small white box that you previously tapped turns orange.
8). Go to the apps screen...you should have no problem playing either Pandora or iHeart Radio....and actually hearing the audio!
9). If you would rather play iPhone music, this is easily accessible from the Bluetooth (BT) option on the Lexus main audio menu, at the top of the screen.

The iPhone software version I am running...on an iPhone 4s is 6.1.3

Hope this is helpful!

The ENFORM app shows pandora paused even though it is playing at different song controlled by connected iphone.

Additionally, when you press "Music" on your iPhone, make sure it is actually playing a song (not paused) when you press the white box with the arrow inside (lower right hand corner). I found, that if the song is paused for some reason, that the Pandora app doesn't work either when you switch to it on the Lexus. Note that we are talking about the Pandora app on the Lexus, NOT the one in the Enform app on your iPhone...hope this helps!
