I got this unit used as is buyer claimed didn't know if worked or not..it wouldnt load it would just come on a blue screen it was stuck on blue splash screen I spent today downloading the 3.1 update got it installed but now its hung on the pioneer start up screen.. I did everything as I was suppose to. They said it could take a little bit for system to adjust to it but its not budging help?!
