Who is the ebay guy?

 

Multiple links earlier in the thread. He sells SD cards.

OEM will not need device ID reprogramming as it is same for same.  The other images floating around are modified 4400 images, and do need a reprogram (also the 8500 image that works well from @asd255)

The Ebay guy claims to have copied an original card. He even calls out the fake cards. Hence it was weird his didn't work with Maestro but OEM replacement did.

Mine says 1.06 too. Maybe they fixed some of these latent issues in 1.06. It is weird that it's not publicly available.

The Ebay card is 1.02.

Also, isn’t the underlying problem that the 16GB card fills up with logs or something? So wouldn’t a 32GB last longer?

It will 

It will work - but as others have said, if you use the Maestro RR - it will no longer work.  You'll need to rewrite/reprogram the serial number (device id) in to the radio, regardless of what it says is there.  You may want to seek out @asd255 for a better alternative with a fully working image / ability to recode the device ID

The OEM replacement card worked with my Maestro no problem. So an image from it should too. I can test that with a burner card when I have time.

I am totally fed up with my AVH-W4500NEX. I've been reading these fourms and watching videos for 5 hours trying to figure out what to do. It's 4 am right now so I'm stuck waiting for Target to open but when they do I am going to purchase a SanDisk Ultra PLUS 32GB SD card and try to use Rufus to burn the AVIC4500only file to the card. Hopefully that works but if not I will buy the new Pioneer card from PacParts and make a copy of that on a nicer SD card like a lot of you guys have been doing. I will keep you guys updated with how things go. Also is there a newer or better version of the firmware than the AVIC4500only file? It seems like that was the most problem free file that's actually available to download. Thanks!

Will 32GB work? I too was struggling to find 16GB. I was going to use a copy and not the original but said screw it. I don't trust Amazon for SD cards.

Thanks @Datsun It seems our images are different in some way.

For others viewing this topic, I purchased one of the official Pioneer SD cards for the AVH-W4500NEX from PacParts.com. Part number QXX3352 (https://www.pacparts.com/part.cfm?part_no=QXX3352&mfg=Pioneer).

I created an image from the card using this command(in linux, MacOS can do this too):

dd if=/dev/sdcard of=/path/to/image.bin bs=512

and then hashed the resulting file with this command:

sha256sum /path/to/image.bin

and the output of that command was:

6a466ff1a69dd147cd5e2601f73bbac4340d70f4ee3436b2db51153552dbaef2  /path/to/image.bin

This doesn't tell me a whole lot other than the simple fact that @Datsun's image and my image are different. There's a million reasons why they could be different.

Has anyone else bought the official replacement SD card, and would they be willing/able to do some coop hacking around with disk images of a fresh-from-the-factory card with me?

I bought the official replacement card. QXX3352 from pacparts.com. The Maestro started working again right away. So something is up with the Ebay cards. The seller wanted me to change the device ID to fix it and sent a PDF instruction. Even though his image is supposedly straight from an original...

I also made a backup image of the card for when this happens again. Here is the sha256sum hash:

i downloaded and install the file w4500img that you had previous , everything is working except lost maestro steering wheel controls, maestro module lost communications with the pioneer , thank you 

What did you end up doing?

Did anyone fix the iDataLink Maestro RR issue for w4500nex without having to purchase OEM? I purchased an SD card off Ebay (this guy: https://www.ebay.com/itm/133889598926) and it, too, won't work with Maestro RR. It sucks not having steering wheel controls but it also causes phantom draining and killing my battery. It took me a while to figure out and 3 Costco warrantied batteries. If I pull the fuses on the radio, no more dead batteries. The Ebay firmware did fix the boot loop but I guess it is not fully compatible with the w4500nex -- likely just the modified w4400 firmware as outlined here. The serial number is unchanged and I flashed the Maestro multiple times. I guess maybe the Maestro or the HU loop until the battery dies when the firmware isn't just right?
