so, i just picked up a new (to me) car that has a f900bt in it.
at the moment the car has no front speakers. only rear (it came this way)
it was on FW 2, & i had a issue with the navigation & BT from my phone being extremly low, almost muted. & sometime when listening to the radio it would mute for a few seconds then come back on
so i dug & dug on this forum through many broken links & finllay updated to FW 3, then Fw 4.
that fixed the mutting when listening to radio, but the navi voice is still extremly low. i went into all the settings & turned it up, but nothing..
does this unit use the front speakers for the navi & BT audio?
