2003 C240 Bluetooth/ Iphone Integration
I'd appreciate any insight!

It is my understanding that after installing the bluetooth bits, you will just have phone capability. I don't think you'll be able to stream music wirelessly. I think to do all that, you'd have to get another HU. I think that is a better option unless the perfectly integrated styling of the OEM HUs is the most important thing to you (touch screens have to be flat so they don't fit perfectly on the dash, but they work well IMOH). You can get bluetooth (streaming & phone), GPS, microSD card slot, iPod, DVD, etc. for not a whole lot more than the parts needed to enable your bluetooth with the OEM HU (and maybe less than the MB retail price for the parts).
Just my $0.02.
