The E90 is equipped with the same TCU that is found in the E60 and E63/4 vehicles only if option code SA639 (Assist or Premium Package) is ordered.

The range of functions offered are as follows:

• The Telematic Control Unit is fitted as standard in order to provide the Telematic functions Emergency call (E-call) and Breakdown call (B-call)
• Dual band 800 MHz and 1900 MHz
• Combined NAD (network access device) transceiver module for the:
  • analog AMPS (American Mobile Phone Standard)
  • digital CDMA (Code Division Multiplex Algorithm) standard

Two different equipment levels are offered for the American market:

• Telematic Control Unit with Telematic functions Emergency call (E-Call) and Breakdown call (B-Call) without base plate or snap-in adapter.
• Telematic Control Unit with Telematic functions Emergency call (E-Call) and Breakdown call (B-Call) with base plate and snap-in adapter for a supported Bluetooth compatible mobile phone.

The telematic control unit is factory-programmed as "active" for Bluetooth. Consequently, any supported  mobile phone can be linked to the vehicle.

The customer also has the facility for charging the mobile phone in the vehicle and making calls via the external aerial. The external aerial reduces the radiation exposure inside the vehicle.

There are optional components available for the TCU:

• Base plate
• Snap-in adapter for Bluetooth-compatible mobile phone
