Zitsky is correct. I have provided pretty extensive help on the audio forum for the GW 500, but I would not call its installation particularly easy. If you know your way around car audio systems, it won't be too bad. However, folks have been having problems using the BTA 1500 with COMAND units; it seems to work with some AudioXX units. You might be better off installing MB phone equipment (see http://www.benzworld.org/forums/aud...13173-how-guide-cell-phone-upgrades-plug.html and read especially the MHI section; follow links).

You could investigate combo phone/iPod units from mObridge and InCarTronics - but you will lose use of your CD changer with those units. The GW 500 lets you keep your CDC.
