Thank you so much for your immediate answer. I will give it a try in a few hours.


What about my other issues? Any time i power off my car all settings go back to default.

I've kinda figured it out. While in test mode i have noticed that my flash disk was full (16kb remaining) and therefore could not even copy greek language in the Lang Folder.


I went to the buildings and POIS folder and deleted some countries e.g. Bulgary and Romania  (6MB space). Then copied greek language.


Afterwards i deleted gpspara0.bin, gpspara1.bin, gpspara2.bin, gpspara3.bin and BOOM!!!!


My avic unit went back to normal. All settings stored and greek language installed.


Your support is really appreciated.


Thank you very much!!!!

can anyone please tell me how to fix my avic f900bt?

After awhile the screen freezes on the welcome image and stays that way. If i insert a CD it works, but the menu button and the maps button are not working.

I updated my device with the latest version 4.0 but it's still the same. The boot button does nothing.

Help please.
