Weird. I've NOT experienced this. I'd disconnect the maestro, etc (ugh, i know) and see if it goes away. I'd also be considering buying a replacement display on eBay to swap and see if the problem persists or resolves. The w4400nex display is also directly compatible - I know cuz I have a w4500 with a w4400 screen. Could be a sticky button on your steering wheel or display unit, or potentially the touchscreen digitizer. Definitely not quick/easy/fun to troubleshoot. I don't envy you.

Glad you got it working! It might be a good idea to warn people that there have been reports of issues when using these images, because they are based on the 4400 firmware (correct me if I'm wrong). IIRC some features don't always work, and if someone wants those features, they may decide they want to pay the $95 to get the official one. I didn't download these again to double-check them against the 4500 firmware image I made from the $95 official SD card I bought. IF someone buys the official card, they too can make a backup file before they install it in their 4500. I went a slightly d

@Jeff Brown Buy the official replacement SD card from PacParts.com (Pioneer QXX3352), see https://www.pacparts.com/model.cfm?model_id=AVHW4500NEX&mfg=Pioneer&back=0&action=list_part. $95 + s&h. BEFORE YOU INSTALL the new SD card, clone it to an image on your hard drive and back that image up for safekeeping. As you hopefully already know, the SD card will be locked after you install it, and no one here knows the SD card lock/unlock password yet. I just did this with my own 4500 (with a slight twist). I cloned the QXX3352 SD card, and then put it back in the packaging

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: 6a466ff1a69dd147cd5e2601f73bbac4340d70f4ee3436b2

So I bought a "used" AVH-W4500NEX online and it appears to be what I would a "Frankenstein" radio (where more than one broken units are reassembled to create a single working unit). Is there a better term to use? For example: the screen module is badged with AVH-W4400NEX in the corner and the serial number on a sticker on the unit does not match what is shown in the system information screen. Since I'm new to these units and have a lot to learn about them, can someone explain how "swappable" parts are between the two models? It seems they're basically the same hardware with a few minor ch

@DatsunAny chance of sharing the .img file you created from the Pacparts card?
