Avic F900bt installed in Alfa has suddenly stopped working.  Has worked fine for three years then after bettery going flat in car stopped loading and doing the notorious reboot then went to the black bricked up screen. Have tried wince upgrade and adding files from user on which has brough the unit back to life partially except cannot access anything except the settings controls...ie no audio, phone settings, maps etc.  Understand will need to reinstal ezrider and maps for this.  Dont have any back up as never expected to play around with the unit as was all working fine till few weeks back.  Really need this going again and do not want to take out of car to send to pioneer who have been far from helpful.  any help and advise much apprecaited.

Hi,

what I would do if I were you is to download the newest maps for iGO 8,3, then backup, then update your device using the newest maps and hybrid 4.01 firmware. Just go through the hybrid 4.01 topic and you will know exactly how to do everything.

Hey, still not fixed? Sorry for late reply...

Curious to know what you did to fix this issue, or if it was fixed in general.
