By the way, i guess i will solve this problem if i could connect my avic to PC. Tried to do it via USB a-a male-male plug, but no results

i don't understand about button - how can i check it if i even can't turn avic on. I just tried different firmware, and as there were no difference, decided to return back to may old one, because there were maps, poi's etc

bump, need help

heh, i thought there is some kind of extra battery in avic % ) thenx) will try this hint.

What do you mean under "Battery checked" ? How did you do it?

Still need help How to install new firmware without testmode? I have already download it. Or maybe it is possible to connect PC via USB, and PC will see the avic as usb device so i can upload new firmware? Nowbody had such problems?

Hi/:) I tried to install European Firmware on my Avic (cause i need even FM frequency). So, everything was ok, but after changing firmware - nothing changed with fm radio. Still only 98,1 - 98,3 -98,5 etc. I decided to return back original firmware (a back up it on usb), after copying and rebooting - avic doesn't want to start. When i turn it on - a see Pioneer logo for about 15 seconds, and after that it turs off/:evil: The same problem if i start SD card with testmode - so i even can't run testmode and change firmware. So i really don't know what to do. excuse
