Radio antennas

684_071

The Audi e-tron GT (type F8) is designed to receive FM and DAB radio (9VD). The relevant antennas are located in the rear window.

On vehicles for the North American market, the SDARS antenna is integrated in the rear lid.

Overview of mobile communication antennas

Wi-Fi and Bluetooth aerials

The vehicle is fitted with a Wi-Fi antenna (wireless data transfer antenna R336) and a Bluetooth antenna (wireless data transfer

antenna 2 R366) to enable the customer to pair external devices. The Wi-Fi antenna is located in the mirror base and the Bluetooth

antenna is located under the rear shelf (right-side). Both antennas are connected to emergency call module control unit and

communication unit J949 (connectivity box).

GPS aerial

The GPS antenna is located in the mirror base and is connected to J949, which calculates the vehicle’s position. This information is

then transferred via Ethernet to infotainment control unit J794, which performs all navigation functions.

Mobile phone aerials

In addition to the Wi-Fi and GPS antennas, one of the four LTE antennas is also located in the mirror base. The other three LTE

antennas are located in the front bumper (left-side), under the rear shelf (left-side) and in the rear lid under the glass trim. The LTE

antenna under the rear shelf is the main antenna. The four antennas are connected to the connectivity box. The signal from the

main antenna, combined with the signal from the LTE antenna with the best reception, is transmitted to the connected gateway

(J533)/the infotainment con-trol unit (J794) via Ethernet in order for the Audi connect services to be performed.

The Audi e-tron GT (type F8) can be fitted with the Audi phone box (charging unit 1 for mobile devices J1146) as optional equip-

ment. Thanks to its connection to the external LTE antenna R330 (in the front bumper, right-side), the Audi phone box improves re-

ception quality while reducing the amount of radio waves from the smartphone inside it that enter the passenger compartment.

Bluetooth Low Energy antennas

Two additional Bluetooth antennas are fitted in the bumpers, one at the front left and the other at the rear right. These two

antennas support the energy-saving Bluetooth Low Energy technology (BLE) and are responsible for the remote park assist plus.

This duplica-tion ensures the best possible coverage of the area around the vehicle.

The BLE technology is fundamentally different from the Bluetooth technology that is used, for example, for HFP or A2DP. The BLE

technology that is supported is version 5.0.

The two antennas are connected to control unit for radio-controlled parking J1182, which is located in the driver’s footwell below

the dash panel. Control unit J1182 reads and evaluates the information that it receives from the two antennas. When an

authorised smartphone is identified, J1182 transmits the status via CAN bus to driver assist systems control unit J1121 (zFAS),

which is re-sponsible for performing the parking maneuver.

Control unit for radio-controlled parking J1182 is not part of the component protection system. Its diagnostic address is “8107 –

antenna module”.

Remote park assist plus

The Audi e-tron GT (type F8) is the first Audi model to be fitted with the remote park assist plus. The remote park assist plus ena-

bles authorised users to park the vehicle or drive it out of a parking space via the myAudi app without having to sit in the vehicle.

The following requirements must be met in order to pair the smartphone with the vehicle:

›

A key user must have been set in the vehicle

The user who wants to use the remote park assist plus must be logged in with his/her myAudi account in the vehicle

The user must be logged in with his/her myAudi account in the myAudi app

Bluetooth must be activated on the smartphone

BLE user identification must be switched on in the myAudi app

As soon as these requirements have been met, the logged in user’s myAudi account calls up the BLE (Bluetooth Low Energy) ID for

the vehicle which the vehicle has already sent to the backend.

When the user logs into the myAudi app, the smartphone’s BLE ID is sent to the backend.

If a key user has not been set or if the user has not logged in correctly in the vehicle using his/her myAudi account, the backend

sends an error code and the myAudi app displays a corresponding message.

The next time the vehicle is started, the backend sends the smartphone’s BLE ID to the vehicle, thereby completing the Bluetooth

pairing for the remote park assist plus.

When using this function, the user must be in the immediate vicinity of the vehicle. If he/she exceeds the maximum distance at any

time, the parking maneuver will be interrupted immediately and a corresponding message will be displayed in the myAudi app. To

enable the distance between the vehicle and the user to be monitored during the parking maneuver, the user must have the vehi-

cle key (not an Audi connect key) on his/her person.
