Not to high jack the thread but that's one thing that disappoints me about MB when it comes to the SLK.
Such an advanced vehicle manufacturer technology wise, yet for example the 350 (pre-facelift) i'm about to get shortly (which is an awesome vehicle btw) won't even have an ipod interface and from what i read unless it has COMAND there's no chance of a retrofit unless its via the aux and i heard some don't even have an aux to begin with...
What's up with that though, even my BMW has all of that in it... damn... The SLK is a great vehicle but i'm big on audio and that's one let down for me personally. /rant
