How to pair my iphone with my Mercedes Benz?

You need to do it through your phone rather than the car. Go to your settings, there should be a link to your bluetooth settings. You will want to scan for the car's bluetooth at the same time. With the older models (i.e.pre 2010) you may have to also be on the bluetooth section of your car's system as well.

If that doesn't work, a quick call to the dealer's service dept. Should work.

The '09 is looking for initiation from your command center (select telephone-pair) accompanied by a search from the iPhone. The entire procedure is documented in the manual for the command system. If you have misplaced yours it is available for download at MBUSA (see link).

Start on page 167.

All you have to do is go into system settings select Bluetooth and turn it on then turn it on on your phone then on the car click search for devices then if you have a password enter it on the car. And do all of this while the car is started or it will not work.
