BT-04 Headset Software
Update Instructions
Win 10 - Google Chrome

This latest v00.2.4 software update has addressed the headset’s ability to remember the last volume setting for the CB radio, along with the on/off linking issues with the current Honda audio system software on the 2018-2021 Gold Wing. (Latest "How-To-Link" Video for the new Wing here )

Now the user will be able to adjust the BT04 headset volume to CB radio maximum while actually receiving a CB transmission or static signal (un-squelched) and the headset will remember this maximum volume setting when using the CB radio. Once this headset volume setting is adjusted for the CB radio on the new Wing, all further CB radio volume adjustments are to made from the handlebar controls only.

When linked to the BluHub Dongle44 or the 2018-2021 GL1833 audio system, the signal to the headset will be in full aptX digital stereo, at the maximum volume setting on the headset, without the need to make this headset volume adjustments manually and all further music volume adjustments are made with the motorcycle handlebar volume control.

When linking to the Harley® WHIM dongle, the BT04 headset will stream mono music from the WHIM while providing all functions of the intercom, cell phone, GPS commands and CB radio thru the Harley Infotainment audio systems.

This latest version 2.4 update also maintains the full stereo operation with the audio systems on the Can-Am Spyder and Indian Ride-Command.

An all new BT04 VOICE prompt package has also been included.
