Service Secret Menu Pioneer Avic N4
1. RESET and EJECT buttons simultaneously.
2. Release RESET button only.
3. When “please push reset button†is displayed, release EJECT button.
4. Enter the password: 8 1 8 3 7 2 0 8
what kind of option does that give you?
What can you do with that?
Sounds like a standard service screen that shows your firmware version, and etc.
BTW, if you press UP UP DOWN DOWN LEFT RIGHT LEFT RIGHT B A B A Select Start,
you get 30 lives in Contra for the NES!

^ Oh Snap
I tried it,
It reset all of the unit's settings back to default (no big deal for me) so be careful if you have your N4 setup "just right".
It looks like you can do a lot of damage in there. You can flash your system's memory, clear nav memory and test sensors and inputs.
cheers
Thanks Ill have to check that out on the next one I do.
Can you turn on RDS? That's what I want to know.
on the d series (should be the same functions in the service menu,)
you can also recalibrate the touchscreen. over the course of three years, the screen on my d1 became way out of whack. pioneer wanted $200 to send it in to get fixed, and it took 10 mins to do myself with the service menu.
also, if you download or update to a newer map dvd, and for some reason have a problem that you want to go back to the original software that came with the unit, putting in an older disk will give you an error message and nothing will happen (putting in a newer disk automatically starts the system update, but it's not backwards-compatible.) the service menu lets you insert a dvd and install that software, no matter what version.
so yes, not knowing what you're doing can cause lots of trouble, but knowing what you're doing can also save you $200.
I can't seem to enter this menu. I get to "please push reset button†step.
How do you enter the password? Do you have to have a remote for this?
Can anyone help with getting into the service menu?
I used a remote but there has to be another way to enter the menu.
Sorry I didn't mention that.
Just looking for an update:
Anybody know how you can access the menu without a remote?
Thanks,
Randy
WTF? I just got A bunch of extra lives for my Avic and there's a guy with a Spray Gun standing in the corner.
bump on this. how to enter? i have the same issue. cant get past RESET. No password prompt
Well I finally got into this menu. I used the Pioneer remote control. You have to slide the switch on the right side of the remote to DVD. 2 is up, 8 is down, 4 is left, 6 is right, 5 is enter, and the 'C' (clear) button in the bottom right corner is 'back'. I didn't find anything interesting in these menu selections. Good luck to those who want to play.
