I have 2004 E500 with DVD-NAV. When I bought it doesn't have phone equipment installed. So the small compartment in the middle is totally blank/empty. I travel a lot and I need to install equipment where the car can detect my phone and connect via bluetooth. So I can speak and the voice will come out from the car's speakers. Anyone knows any shops that can do this? How much will this cost me?

 

I had an 04 with integrated OEM phone in the console. It worked great, and was an enjoyable option.
