Coms, Nav6 and phone linked...but

The sat nav takes over?

I get on the bike, link phone with sat nav, turn on headset and link with mate.

We set off and chat away all is good.
Then the ding ding ding sounds to alert speed cameras etc... and now i cant hear my mate its sat nav only.
I press the link on side of helmet and hes back.... then ding ding ding....
rinse and repeat!

its feckin annoying thats what it is hahaha

Anyone know a work around, or cant it be done? do have to choose between the Nav6 and my mate... ie turn the bluetooth off on the Nav?

Turn off audio alerts and try and rely on the pop ups on the screen catching your eye?
