Information On Re-enabling The NAD

Re-enabling the internal telephone module

Sequence for re-enabling the internal telephone module

In the event that the internal telephone module has been disabled by the Telematics provider (e.g.: end of contract), there is the possibility to re-enable the module by means of this sequence. To do so, it is necessary to enter the MIN (Mobile Identification Number) and the MDN (static phone number of the internal telephone module) manually. Please keep the MIN and MDN required for this control module on hand.
