So my AVH-W4400NEX started bootlooping and I used the excellent post by @HondaR to get it back up and running (replaced the internal SD card). Along the way I saw that you can pay money to add backup camera lines and navigation by using the AVH2AVIC Image or SD Card ($50 or $65 available by contacting @asd255 or buying an SD card on eBay and waiting a month https://www.ebay.com/itm/114825169620). In researching around, it looks like @slackwaredragon might have figured a way to modify the image so that it looks like a W8500NEX (based on this post
). Has anybody made that modification without paying $$? I would love to add backup camera lines to my W4400NEX (I don't care that much about navigation). Has anybody done this successfully on the AVH-W4400NEX who would be willing to share their method?
