4000Nex Stuck in Boot Loop

Recommended Posts

My 4000Nex recently stopped working on me after 2 years of regular use. It would boot to the screen with the Pioneer logo and "Loading..." for about 15 seconds and restart over and over. I have tried:

 

-Disconnecting the car battery

-Pressing the tiny reset button

 

I believe the internal SD card is corrupted and will need to be replaced. Where can I find instructions on replacing the SD card and flashing the new SD card with the backup image?

 

Thanks!

Hi Jerry, 

 

I am in the same exact boat. Had the unit for 2 years then it started to do the continuous boot screen restarts. I pulled out the internal SD and found that it wasn't recognized by a Windows or Mac system.  Still waiting for a backup img for the 4000nex. 

 

The internal SD card is located below the CD transport on the front right side. See the photo in the link below.
