Mercedes introduces an optional Motorola Dual Band Phone with Bluetooth handset for the E55 AMG (and of course other E-class models) starting August 2003.
Linguatronic can be added as another option too.
The new phone can be also operated through the display of the APS50/COMAND APS, even allowing to surf WAP sites.
I don't have any information if this phone option is available to the US too.
