This eBay listing is for an SD Card only.
If your pioneer avh-w4500nex radio is stuck in a boot loop (see pictures) or shows a software error screen, you can replace the internal SD card with the one from this listing to fix it.
This SD Card has OEM firmware/software. Carplay, android auto, Reverse Camera Parking guide lines, Maestro, weblink ALL work!
Comes on a high-speed high-quality name brand (SanDisk) Class 10 SD Card, UHS-I bus speed (should boot faster and run better than with the class which radio originally comes with)
Please reach out with any questions. I'm happy to help guide you through the process of getting access to and replacing the internal SD Card.
I have made a little album to help guide through the process of replacing the sd card:

You should have enough room to be able to access and replace the internal sd card after you pull the black frame out as described in the image.
A youtube user "Van with Tim" has also made a video that guides you through this process. His video does a few more steps than mine.
