Has ANYONE had a bootup issue with their avic's which hangs up after the boot up screen disapeers to the startup screen. Sometimes i can get it to boot up fully by hitting the map key that takes it to the nav disclaimer, hit ok and then the damn thing works as normal! freaking thing is P.M.Off!! Sometimes it just hangs on a black screen, no restart just in limbo. If i hit the reset for 5 seconds and then let it start up again and of course after the logo goes off hit the magic map button it says "system starting up". DOES ANYBODY have any ideas, i have had the radio for 4 months now (Pioneer says no warranty, refurb!) have spent $800 for all the sat, hd, ipod cables etc and this is killing me. My wife nagged me for 3 months about buying it and now........well u know shes loving life 
I tried to install the update on an SD card hoping it would cure it, wont even begin to update!! PLEASE help, i love this radio and i cant let my wife get the last laugh.
