I've got the AVICZ1 almost into its service menu by opening the face, then pressing the reset in and holding the eject button under the face in then releaseing the reset, but I cannot figure out how to enter the "UP - UP - DOWN - DOWN - ENTER" code that i've used on the AVICD2 and AVICN3.
Anybody got into the SERVICE / DEBUG menu on the Z1?
I didn't even know that was there. What buttons did you use on the D2?
Volume? What did you use for enter?
I would think that you could use the same buttons, Vol up and vol down and whatever you used as enter.
for the AVICD2, while the unit is in normal operation with the ACC and 12V powered up, hold the open button so that the DVD eject button is revealed, then press the reset button in with a paper clip, and HOLD the DVD eject button. Continue to hold the DVD eject button and release the RESET button. The unit will power up and say somthing about hitting reset. Instead of doing that, press the 'open' key so that you can see the screen again and then enter the super-secret code "UP - UP - DOWN - DOWN - SELECT" using the joystick thing. It will boot into a special service menu.
Well on the D2 you use the joystick.
The joystick moves up/down to move the playlists up and down, and left and right to go to the nexzt or previous track.
Try using those buttons on the Z1.
I got in!
1. Open the face.
2. Hold Eject.
3. Press Reset
4. Once screen says "Push Reset button or Restart Engine" release eject button. LEAVE THE TOUCH SCREEN OPEN!
It took me a while because it allows you to enter 8 buttons before it stops beeping, but by pushing th AV button would make a sound after the beeps stopped. The AV button acts as the backspace button, so if you enter the code wrong, just hit the AV button until it stops beeping and start over. If you closed the touch screen simply push the AV button (should only beep once since it only has to clear the one input button you pushed; the open close button.)
Anyways, the password is:
P.LIST UP
P.LIST UP
P.LIST DOWN
P.LIST DOWN
T (T is always enter)
If the service Menu appears, close the touch screen.
Now it will show a service screen, looks like it is mostly for clearing memory. But TRACK LEFT and TRACK RIGHT will take you to other menus, three in total. Menu 2 is HDD related stuff, and Menu 3 has one option simply called "Bluetooth Device"
I didn't want to play a lot with the menus tonight, but tomorrow I will. I'm sure some of you will be up all night with this.
Menu 2 has an option that gives you access to all of the folder (maybe files) on the Z1 HDD, like I said, I didn't play too much. But, this maybe very helpful to those trying to crack the HDD or just maybe (fingers crossed) add/delete files to the HDD.
Here is a pic of the service screen, pretty simple. Like I said before, use the Track left and right buttons to change menus.
AV is always BACK.
T is always ENTER.
the rest should be pretty simple since they are listed at the button.
I really need to clean my screen. 
oh wow, the menu allows you to browse the entire contents of the harddrive. i noticed that the music is all in .AT3 format which i believe is ATRAC3 ................. VERY intresting....
I got into this on my AVIC-N1 and made some changes, but i need to save & exit - I couldn't figure out how to do that - anyone successfully made changes & exited the service menu? I know it will be slightly different on my unit, but at least I will have something to look for if I have an example - thanks

You only have to ask once. Posting the same question across different threads is a good way to get ignored. No offence, just trying to help.

I posted in this Z1 hack/mod forum to try to get help from people who wouldn't see my post in the N1 forum - for example, I am a member of the benzworld.org forum, but I only look in the SLK section, so I wouldn't see a similar question in the SL section - all I need is a simple answer from people who have obviously been in the menu and saved their settings! If I can learn how it worked on a Z1, I might be able to figure it out on an N1 - thanks for your help!
hey guyts, ive been out of town for a few weeks, but have been dyeing to get home to try this on my z1. anyone know if we can do anything useful via this method?
Any updates on this?
Has anyone found any useful info/tricks by using the service menu?
I am particularly interested in clearing out the Bluetooth list of registered phones (starting from scratch) as well as the .at3 audio format for music.
You don't need the service menu to do this, just do a level 4 reset
