So I have the following problem:
My bluetooth menu disappeared from original GPS Menu.
I tried to turn it back with factory settings but with no success.
Tried to reset it by reset button, but without success again.
Bluetooth is working because i tried it from other menu system, but it disappeared from original menu.
Please help me to solve this problem, I appreciate your help.

I'm looking also for original firmware, and if it is possible someone to tell me how to download original firmware from the navigation.

u mean the icon disappear or what ?? can u show some picture so can see clearly .

@intesa

You have to describe the history of event that you have done leading to the "disappearing". I believe that you have flash your current hardware with an updated or another version of firmware together with the application too. The 'disappering' always occurs because most of the released firmware aplication come standard without bluetooth menu. You have to find the application with bluetooth menu in YFAPP

Hello, I beg your forgiveness for my English. I'm from Argentina and I have the same GPS, and I to result in the same problem. I have no Bluetooth icon and FM transmission is bad because it or heard it played in the GPS enabled this option.
If anyone has any idea or have any answer to this problem would appreciate that.

Greetings!
