This is an image of the internal sd card of a AVH-W4400NEX. You will need to dissemble the unit to access the card. It is android based receiver so will have a android partition layout.  If you try to copy it to a fat32 formatted card it will fail.

To write the image to a sd card:

1. download zip and extract the img somewhere

I extracted the image to /tmp/AVIC.img

2. find the device name of your sd card 

sudo fdisk -l

Take note of how the SD card is identified.
In my case it is /dev/mmcblk0
3. Write the image to the sd card

dd if=/tmp/AVIC.img of=/dev/mmcblk0 bs=1048576

4. insert the card into the receiver and your done

I attempted this on a windows computer using WIN32 disk imager and head unit boots but there is no response from the touch screen. Any recommendations?
