Hello I have a Pioneer AVIC – 5201NEX unit had a flash screen repeating over and over. I'm wondering if it's the SD card and hoping that someone here may have the software that I could download onto that new SD card and try it in the unit. Thank you for your help 

I just purchased a new sd card and havent inserted it into my radio yet, trying to figure out how to make an image from it but not having any luck.  I have the same head unit as you.  If someone can tell me what to do I will gladly share my image.

Once you put it in your unit it will lock the card and you won’t be able to do any other thing with it like create an image. 

I had researched this enough to know that, so I still have not installed it into my head unit.  I am going to attempt to make a back up image of later today if I can make time.

Thanks!
