C180 Coupe, early 2003, Audio 10 - ipod connection

[Paul Savage]

I am sorry if this has been asked many times before, but what are the latest best options for connecting iphone ( for music not calls) to a C180 coupe please? It does not have a CD autochanger fitted. It has the simple single CD audio 10.
Please give me an idea of best buys to look at and where any fitting guides may be.
Thanks all.
