How to get GPS audio instructions on mobile phone

[LordF]

I've a new Rider 550 and it is connected to my mobile via Bluetooth. It can also connect to my headset on the helm for GPS audio instructions.
What I prefer is to have these instructions to my mobile phone and have them on my 3.5mm audio jack routed into my headset. This way I can communicate with my partner and hear the instruction from my TomTom simultaneously without having to switch between the 2 BT channels manually.

I don't need to be able to make/receive calls, nor receive any info about it etc. I just want my GPS audio

Does anyone have an idea how to get this done?

Thanks in advance

You cannot send voice instructions from your GPS to your phone.

The GPS can only connect to a headset for voice instructions and to the phone to receive live traffic information.

Was already afraid for that. Thanks anyway for your quick reply.
