Well I have some good news! I did some testing today and can confirm that the 32gb SD cards work great! I tried a Sandisk Extreme and an Extreme Pro and they both work well. As for the software I tried both the AVIC4500only file and a copy of the OEM SD card. Both seem to actually work really well but the AVIC4500only was version 1.02 of the firmware and the OEM SD card was version 1.06. I don't have steering wheel controls so I couldn't test those unfortunately. The headunit seems faster with the new SD cards and it is also way less buggy. I think my original SD card was pretty full for a while as my headunit got really buggy before totally giving out. Also the original SD card had version 1.00 firmware with no way to update it which is kinda werid. Pioneer really needs to support their products better

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.

So I just burned the AVIC4500only file to my 32gb SD card. I didn't really feel like opening the unit so I just dremeled a hole in it. Not pretty but now I have easy access to the SD card. Wish me luck guys, I really hope this works. I'm still going to try to get the original W4500NEX software somehow eventually but hopfully this will bring my headunit back to life for now.

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!
