Connecting Iphone 5s to ky 2005 E320
 

I would like to be able to listen to my music and use the phone through the car stereo. The car does not have any adapters or connectors (or anything else) in the arm rest, but I do have the AUX port in the glove compartment and the navigation system. I love my car, but know nothing technical about it. I would appreciate simple, easy to follow instructions or product recommendations! Thanks!
