I've bought recently a new car were a avic F900BT was installed (with firmware 2.009)

 

the problem was that it didn't recognise my sd card or USB card

i thought that after i update it, maybe it will recognise my sd card

i found out that if my sd card is smaller then 1Gb it's recognised, (is a pity because i have more music then 1GB)

but after i put the update firmware (downloaded from pioneer site) on the sd card

it doesn't recognise the update firmware.

if i put music and the firmware on the sd it recognises the music but not the firmware

 

if i can't update the radio can i make sure that it recognises more then 1 gb

There isnt any other updates on the pioneer site to upgrade it higher than 2.009, you have to do it manually using downloads from this site.

 

As for the sd card, my unit will recognise 4gb cards no problem so there must be something wrong there. Maybe a cheap sd card?

I live in the netherlands and on the pioneer.eu there are updates to version 3 and 4,

and the de card had worked in a Pioneer avh300.
