Adding ipod/blutooth capability
 

I have a 2006 E 320 CDI sedan. It came to me (used) with an Ipod hookup coming out of the glove compartment. It's an older interface and does not charge my current Iphone 4s or my wife's ipad. Is there a product I can add or replace that will allow me the ability to charge and use my current Apple products? What about Blutooth phone capability?
Any assistance is appreciated!

Is the iPod hookup in the glove compartment the cable or like a charging dock?
