Try this.

Ah ha. I guess I missed that posting.

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.

This is just my opinion but the bottom of the screen comes out and the top drops down. I would try to pry out the bottom, carefully, and push down the top. Granted I have never done this but I don’t remember it “latching” when it closes. Then then if it comes out there is a little slider latch, I think it is on the right side, that you move to remove the faceplate from the holding track. Sorry I am currently in my wife car and don’t have access to my unit right. I mean shucks what do you have to lose by trying. Just my opinion.

Glad something I posted actually helped someone here. Great News on you fixing the issue.

Looks like the firmware is on the Pioneer website for this unit. Free.

I did not. Here is the listing.

Did you put the card in the correct slot ? There are two slots.

If I remember correctly there was something in the The AVIC Development Mod thread. But it involves modifying the software on the sd card to get the “caution” screen to go away. Since I own a w4500 I’m not sure if it would be the same for your unit. On mine it goes away after a minute or so, I just pay no attention to it. Just trying to point you in the right direction. I am no coder, but maybe asd255 can help, he seems to me to be very knowledgeable about these units.

Happy to help.

Glad I was some kinda help. Definitely worked for me, made it easy peasy. And if it happens again, burn a new card and replace the card.

I have the official w4500 firmware and looking thru the sysd.conf file I seen there settings in it for 26 different models. One being the AVH-Z9200DAB.

I just hope it helps you. I was frustrated for a long time reading any and everything I could on here before I finally got it right. Good luck.

When I used it I used a cheap sd card I bought on Amazon. It worked for a while, a very short while. Then I ponied up and bought a 16gb, class 10 San Disc sd card. Used my Linux Mint to image it on there and have no issues since. I might have screwed it up in the Windows machine, it was my first attempt at doing this or it just might’ve been the cheap card.
