I have a Pioneer Avic F840BT which is running firmware 4.00.
On Pioneer website I have downloaded the 4.01 firmware update. http://www.pioneer.eu/uk/support/software/AVIC-F840BT/page.html
However when I unzip file AVIC-F40BT_Ver4.01.zip I am presented with a folder AVICZ110 which I have copied onto the root on my Micro SD card.
The problem is when I insert my Micro SD card into the F840BT unit no update screens pop up and I cannot figure out why. I have used the card to do a radio update which works fine and add POI files to which also work fine but when I try the firmware update to 4.01 it doesn't work.
Any ideas why?
