OK, when I try to go into service mode, I press eject, menu, map, and reset. As soon as I release the reset button, it goes to the blue screen where I can input my codes. I thought that when I release the reset button, and hold the other 3 I was supposed to get a "pop" from the speakers, but nothing, goes right to blue.
I can put the codes in, and it says that the unit is reading the WINCEIMAGE.Bin and WinCEImage.CKS files, comes up with the reset message.
I shut the truck off, put in the pioneer updates, turn it on, goes to pioneer screen for a few seconds, and then goes black agai
