Hello;

   Bought unit last summer.  Worked great till last month, and one morning the IGO maps wouldn't load. 

Pioneer said it was an issue, but that there was a firmware update to fix this. Sent me the link to the pioneer firmware site.

USB1 on unit works great for music, and video. But for the life of me it would not see the update folder that was copied to it. 

Tried about 7 different brand and size usb sticks. 

   Then one morning, gave it another go. The update started, but failed after about 6 minutes. Said it would restart and 'auto recover'. 

I waited 40 min, with the key on and nothing happened, then my car said low batter and I had to shut it down. 

Now the thing won't even boot. Sometimes the backup camera will switch on, but most of the time nothing. 

I heard there may be a internal SDcard that I can flash, that would fix this issue. I just can't seem to find any info on this,

or where to get a avic-5201nex image of the sdcard.

Can someone send me some info on how to fix this? Thank you
