AUX cable to a suitable audio source.
To play back the AUX audio source, press the source

Bluetooth® indicator (a) appears in the display, or briefly
press the Bluetooth® button (11) regardless of the current

– If the radio has already been connected to an external au-
dio source via Bluetooth® and if this audio source is avail-
able, a connection to this audio source will automatically
be established.
– If no saved audio sources are available, the search pro-
cess will start. Activate the new connection via the ex-
ternal audio source. For smartphones, that is generally
possible via the settings in the Bluetooth® menu. The ra-
dio will appear as an available source under the name
GPB 18V‑2 C xxxx or GPB 18V‑2 SC xxxx. Please ob-
serve the operating instructions for your audio source/

needs to be searched for (PAIRING), press the
Bluetooth® button (11) for longer than 0.5 seconds. Ac-
tivate the connection as described above.
As soon as an audio source is connected via Bluetooth®, the
Bluetooth® indicator (a) will light up continuously.
GPB 18V‑2 SC: The name of the device connected via
Bluetooth® is displayed on the top line of the multi-function
indicator (k). The text from the connected device appears
on the bottom line.
If no connection can be established via Bluetooth®, the radio
will switch off automatically after 19 minutes.
The audio source connected via Bluetooth® can also be con-
trolled via the radio:
– To select a track and to start playback, briefly press the
seek button (scan up) (9) or the seek button (scan
down) (10) until the required track has been reached.

hold the seek (scan up) button (9) or the seek (scan

saved in the last used radio operating mode.
Playback with True Wireless Stereo (with Bluetooth®
audio source)
If an audio source is played back via Bluetooth®, the true
wireless stereo (TWS) function can be activated. Two radios
(either GPB 18V‑2 C or GPB 18V‑2 SC) can be used as right-
hand and left-hand speakers for the same playback.
Activating the true wireless stereo function:
– One of the two radios must already be connected to the
audio source via Bluetooth®.
– Selecting the radio as the right-hand speaker: Select from
the menu <TWS> → <TWSR> (GPB 18V‑2 C) or
<TWS> → <TWS Right> (GPB 18V‑2 SC).
– Selecting the radio as the left-hand speaker: Select from
the menu <TWS> → <TWSL> (GPB 18V‑2 C) or
<TWS> → <TWS Left> (GPB 18V‑2 SC).

radio as well.

dio.
– Control the playback via Bluetooth® as usual.
