I have a 2019 Highlander XLE and I use Bluetooth audio to play music from my iPhone. One thing that annoys me is that when the navigation system provides instructions, the music audio is now lowered or muted so that I can completely hear the instructions.
Yes, I have set the navigation voice to maximum but by not lowering/muting the current music/audio volume, it's not enough. I have really, really lower my music volume when using the navigation and that bothers me. I am truly surprised by this because in other automobiles I've had or used, when the navigation system speaks, the music/current audio is always muted or significantly lowered.
Is it because of the Bluetooth connection or is there something I can do to resolve?
