F900-BT no navi voice, speed camera warning sound

[Cr@zY FreD]

Hi

 

i have a AVIC F900-BT

 

it is an American version i have loaded with Australian maps

 

have got a few speeding fine lately so have turned on the overspeed warning, but it doesn't make any sound, it does cut out the radio/cd for a second but there is no sound

so i tested the nav that has no sound either and it doesn't make any sound when i press a button even when i turn on button sounds ???

 

I think it is something to do with a setting in the sys.txt or maybe i have selected the nav voice i have selected is not installed ???

 

Thanks for any help on this

Have solved 33% of my problems, the nav guidance voice, overspeed alert and button sounds all come throught the front channels and i was only using the rear and subwoofer channels

 

so have connected a small speaker to the front right channel and now the button sounds work but the nav guidance voice and overspeed alert still don't work ???

 

please help people
