Apologies if this has been answered already on the forum. I did some searches and I want to be sure I'm getting the right stuff.

My wife just got an MCS with Harmon Kardon. There is no aux input.

I'd like to be able to 1) plug in the iPhone to a USB cable and play music through the factory radio and 2) make handsfree calling.

What do I need to buy to do that?

Is this unit from Grom with the $49 bluetooth extension the thing to get? http://gromaudio.com/store/usb_adapt...d_car_kit.html

Will I need the DSP bypass because Harmon Kardon?

If there's something that's better or just as good and cheaper I'm up for that too.

Thanks in advance.
