I have an AVIC7200NEX, It has Ver 1.01 BIOS on it.

I would like to update to 1.04.

I downloaded the files, extracted them to the root of USB drive, connected to USB port 1.

Continued through the menus to the firmware update, and it tells more only the update file must be on the USB.

There's a bunch of folders and files in the extracted zip.

So, what is the file needed to flash 1.04? (and then the bluetooth as well?)

Thanks,

Make sure the usb is formatted at fat32 i believe

It is, the NEX is seeing the USB drive, and can see the files, as it tells me 'only the update file' has to be on it.

Thanks,

sigh... this is so frustrating... 

Can't flash the device, and can't use my phone over USB 

$1200 bucks down the drain?

Please help!

Make sure the folder â€AVICAVH16" is at the root of your fat32 formatted USB stick plugged into USB1. When you open up the USB drive on your computer you should only see one folder.

Thank you, I got it updated.

Bad news is, its still not working.

I can't understand why I can not browse my music files... just randomly select songs off my entire collection?!

So, Android auto is working through the USB, and bluetooth does work, but I still don't have access to my music.

When the little bars light up, and I select them, it shows a folder, of "MUSIC2"

There is no MUSIC2 folder on my device?

Do I need to create one, and put my music in there?

Android Auto currently appears to only support streaming music apps like Spotify, Pandora, Google Play Music, etc..

If you want to listen to music over USB I would suggest loading your music onto a USB thumb drive or an iPod where you can make playlists and better sort through your collection.

I don't think the pioneer units were designed to read music from your phone directly. There is Bluetooth streaming for that.

My current setup is AA with an iPod and it works perfectly.
