Why does inserting SD card into AVIC seem to kill it?

Why does inserting SD card into AVIC seem to kill it?  Is there a way to get these "dead" cards to be recognized in Windows again?

Thanks!

It is my understanding that the unit password protects the cards and nobody here that I am aware of knows the password. I’m pretty sure I seen a posting here of someone who used, I believe it was Disc Manager, to re-format the cards.

Hi Mr. Bonee!  I do not think a password would help me, my card reader does not recognize the SD card when I put it in, Windows keeps asking for it.  I do want to thank whoever put up a thing called AVIC.img on Google drive.  I had a time downloading it! I tried direct download and got a redirect warning, then tried a decrypting download but after it was decrypted and I tried to download the page said it was too big.  So I tried the decrypt again and when it was finished I right clicked the encrypted 3 gig file and it came into my computer slick as a whistle.  I wrote the image file onto a 16 gig TF in an SD adapter and stuck it into my AVIC-5100 and voila! It was working again, but there was this VW hubcap thing on the screen.  Then I downgraded the firmware from this 1.6 I think it was to 1.11 which I guess was the last official Pioneer firmware.  I still had the hubcap but I was able to find the picture I was used to.

I know I bumbled my way through this and I owe my success to what I picked up stumbling through this site that I am very grateful for. The whole thing started because I bought a map update off Ebay and the seller never gave me instructions and still has not.  I tried putting the USB drive I received into the unit to see if it would auto installed and this is where I pulled my bloomer.  When the radio rebooted I had the file error screen.  So thanks to all those who made my radio work again.

What's the pass?

What is the SD Card password?

I now have two SD cards that Windows won't see in the reader.  By what method and means would I apply this password if my computer won't even recognize that the card is in the reader?  Will the card reader see the card under Unix?  Is there a Unix environment that runs on windows so I can access the card if indeed Unix will?  Is the password applied through the testmode program?  If so is there a quick start on using testmode?  I just want my cards back.  Knowledge is a fine thing to have, it has far greater value when it is shared.

Thats the old password. It doesn't work anymore.

**correction, that password doesn't work on some models anymore

There is no way to do this on windows or any sort of VM.

You need Linux with a patched kernel that allows you to execute a special command called CMD42 that locks and unlocks and can erase SD cards.

You also need the right hardware. You have to have a built-in SD card reader that connects to your motherboard via a PCI bridge, not USB bridge. Thats why a USB adapter won't work.
