Cellular Telephones And Two-Way Radios Cannot Be Operated Within The Vehicle Without A Separate External Antenna

WARNING: This page is about a different car, the 2014 Volkswagen Touareg, 2013 Volkswagen Touareg, 2012 Volkswagen Touareg, and 2011 Volkswagen Touareg. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

This does not include the proper operation of the cellular telephone preparation "UHV LOW" and "UHV Premium" via which the corresponding Bluetooth wireless signals in the vehicle interior are transmitted between the Cellular Telephone -R54- and Cell Phone Operating Electronics Control Module -J412-. The transmitting power is limited to 1mW (transmission class III),

An antenna cable connection to a corresponding external antenna must be present at the telephone baseplate or the telephone transceiver.

Radio remote controls (for example, a garage door opener) and wireless units (for example, a keyboard) may only be used in the vehicle if the transmitted output is a maximum of 100mW.
Installation of "e-marked units" is only permitted (Europe only).
Cellular telephones or other retrofitted two-way units (business equipment) must have a "CE mark" (Europe only).
Observe the operating instructions and installation instructions of the manufacturer of cellular telephones, two-way radios, and antennas.
The devices' optimal range will only be reached with an exterior antenna.
When telephone and two-way radio systems are installed correctly there is no danger to safety system such as ABS or airbags. A prerequisite is however that there has been no intervention in their installations. Parallel wiring to such systems must be avoided.
Excessively high electromagnetic fields can arise if cellular telephones and two-way radios, with or without an incorrectly installed exterior antenna, are used.

In such a case, damage to health and interference with vehicle electronics cannot be ruled out.
