I have a 2006 ML 350 with the 318 Trim package which includes "Tele aid digital and prewiring cell phone". What does this allow me to interface with and can I use the MB Bluetooth adaptor with this set up? Do I have to get a special phone?

Have a look in the centre armrest top section, is there a connector in there like this: -

(may have a cover on it)

If so, then the phone system is present and you can just add a MB bluetooth adapter, such as this one: -

Comand Online Ltd :: Phone Cradles & Adapters :: Mercedes MHI Bluetooth Module (North America Vehicles)

(if you register , you will see prices minus our 15% sales tax)

If not, you need to first add the phone controller and completer kit, which you'll have to get from a USA/CA dealer (since North America cars are wired differently to everywhere else)
