Hello. I am writing from Georgia, Tbilisi. I need your help so much, because there is not a professional who can help me with my problem. I have a Peoneer Avic-X940BT. While updating the firmware, there were wriiten "an error" After that, it does not turn on at all. Is stopped and the system has no reaction. I think the flash memory has a problem where the firmware is installed. Do you know what the problem might be? How can I solve this problem? Or, what model internal flash memory did the firmware use that I could buy.I downloaded the firware file from an unofficial site.I can send you all the photos of flash memories"chip", which are installed on my navigation. And can you tell me which of these internal flash memory the firmware is installed on?
