Hi to all!!

I'm a new user in forum,i search for my problem but i can not find something..

I have a pioneer f700bt, and doesn't appear pioneer logo.. 

it starts from the main menu screen,and i can't find my fimware..

Also, it reboots after 2-3 minutes it shelf..

Can you tell me,there is any way to fix that?

i need something for europe (maps or anything else..),because i'm from Greece

Thanks for your time!!
