The headset provides the audio mixer feature with a GPS navigation device which can be set in the BK-S2 tool downloadable from www.openroad.com.tw.
Note: These BT devices need to support HFP format, such as the Garmin Zumo series.

Instant Link mode

There can be a maximum of 6 headsets paired together for intercom in instant link mode. No matter what is the number of headsets to be paired, the pairing procedure is all the same. There will be one headset that acts as the active pairing device while all other headsets act as passive pairing devices. The following are two examples to illustrate pairing 2 headsets and pairing 6 headsets.
After the pairing is completed, the next time when any headset of the pairing group activates the intercom, the group intercom commences immediately. Even if any headset of the group leaves, the other group members stay on the intercom without being affected. When that member rejoins the group again, it will resume the intercom automatically.
The pairing data of instant link mode is saved after power off, so there is no need to go through the pairing procedure while powering on again. However, if there are new members that join the group intercom, the pairing procedure needs to be executed again.
To pair more than 3 headsets (including 3 headsets), the headsets need to be set as instant link mode. With the headset powered off, press the A and M buttons at the same time for 2 seconds until the LED flashes blue 5 times to complete the setting.
Note: The pairing data will be erased when the headsets switch between instant link mode and dual music sharing mode, while the pairing data between the headset and other BT devices will be kept. Make sure the headsets are in the same mode to pair and to intercom with other headsets.
