Could you just PM me here, I'm not very familiar with slack

Where can I retrieve that one from? And also, is it the same testmode.key for all the pioneer headunits out of curiosity?

Hey guys, first post here. I haven't been able to find anything on password recovery for the 4200NEX. What files do I need to put this headunit into test mode? Also, the SD card slot is behind the screen and requires a password to access so I only have the rear usb port. Is there a way to get into test mode from that port? Thanks for any help ahead of time, I just bought this car and the previous owner is unresponsive.
