Make sure the parking brake wire is earthed as until it is with normal firmware you can not access most of the settings.

If these are like the Avic F900Bt then i would say the parking brake wire needs grounded as you cant access the system settings on the F900BT without the parking brake connected/grounded.

All sorted and working again went right back to original firmware then re updated to the newest and hey presto bluetooth fixed.

Tried the update files none worked think the actual module parrot chip on the navi baord may be kaput i have a spare navi board that is totally knackered witll look at swapping the parrot chip across to the working board.

Tried the firmware reinstall no change and there is no bluetooth file i think that is what is mising,and tried the link but no go if it has a bluetooth file that is all i would need.

Nearly 600 views and no advice,getting help on here is like having toothache painful lol.

And this is what is shown.

Im having problems with the bluetooth on my f900bt it is now driving me insane,it does not show up in the bluetooth settings where you can update it just says version none and when i try to update it all it does is throw an error messgae up im gettin peed off with it now any help on this if any.

Update tried every guide on the forum to try and fix this and none of them worked,testmode etc made no difference so has anyone got any other info on what it could be the unithas power but was making a noise as if it was trying to boot but all that was happening was the buttons just kept pulsating blue but the screen remained black

Anyone got any spare parts for obe of these like a fully working mothereboard etc probably not.

NO ONE ???????????????????????

Anyone got any idea what is going on with this unit or is this site now obsolete.

Hi recently got a F900BT but it will not start up onto the screen all it does is illuminate the buttons lights blue for say 10-15 seconds then they go out the fan is still running but that is it,i have tried to get to test mode service mode and the unit just pulsates the buttons blue on and off so im thinking that it may be the screen or am i thinking wrong any help on this would be great im in the uk by the way.

Anyone know if this fix will work as i have managed to find the neccessary files just before i give it a try.

Hi new here and was trying to get the files to try and fix an avic f900bt in the uk that is just lighting the buttons up blue for around 15 seconds then switching off,hopefully this will fix it. Thank,s in advance.
