I have a 2005 TL and what to have my iphone 4S tied into my stereo. I want to be able to hear my music, pandora, iTunes, and maybe have it display on my non nav screen? Having it display the song is not a big deal. What is the best solution?

 

The USA Spec is plug-n-play, and integrates with your steering wheel controls.

 

iSimple is plug n play as well . When i plug my iphone 4s into the iSimple , i can stream iHeartRadio threw it and control everything threw the radio controls.

 

Another vote for the iSimple PXAMG. I love this device.
