hello, Today I give you the necessary files to enter into the factory service of Pioneer AVH4000 the reset or clear the password. this's the file: DOWNLOAD HERE i f you do grab my rar compressed file, please make sure that you extr a c t the individual files before copying them over to your thumb driv e . The port that you need to plug the thumb drive into is "port 1". On m y unit, AVH-4000NEX, port 1 is the top rear port. Power up the unit. You should first see the password page, then after a little more time, the Factory Service Menu. Scroll down, select and e xecute "factory re set". Then : "Factory Fre sh Unit"!! ! >I hope that this helps you save the time and effort that I went throug h and/or throwing out $$$ to pay some greedy person on Ebay, most likely for exactly the same procedure that I've des cribed in this post. Good luck 😊
