I never used App Mode - didn't even know it worked with a nano. I can only suggest doing a hard reset by disconnecting the car battery for a couple minutes. This often cures odd behavior after a firmware update.

What do you mean? how is your iPod connected? Did you try AV System Settings/App Connection?

Hold the eject button for about 5 seconds. You might need to cycle the power while holding the eject. BTW, if you got that error you did something wrong. Do not modify any files on the SD except cardinfo.cif (if necessary). BTW, the instruction in that link are to restart the install. The way to abort the install is - put the super testmode.key on a SD or usb, put that in, and it should boot to testmode. go into file maintenance, and remove the file: USER\SYSTEM\Download\StartKnd.log this will kick the unit out of upgrade mode, and should restart into regular mode on next power up (remember to remove the TestMode SD).

Try turning off Demo Mode in the Navi Settings menu. Download the manual pdf from Pioneer's web site. It is easily searched.

Yeah, it's really tough to find the easy way. Did you see the thread at the top of this sub-forum?

No rocks, but: #1 Whoever figured out that old hack (pionera???) doesn't seem to be around anymore. So the shortfuse hack worked and will probably always work for these old units. On that other hardware, you are on your own. #2 Yes. Jason rehosted and converted to a newer BB software. I guess some things didn't (or couldn't) get ported. It does seem to have severly cut down on spammers, but that's the only thing I like about it. But nobody asked me.

Try cleaning the SD contacts or reformating.

If it works now, it will work with 5.1. That was a patch to 5.0 to fix some issues with Apple Lighting support. BTW, it is still on Pioneer USA's site: Software Downloads Scroll down to X940 5.1 update. Read the instructions before installing.

Keepin mind that you don't currently have a x-940, you have a X920 running v5.0 firmware. In the 5.1 update it clearly says:

Got it. Pioneer_2017_maps-Z110-CRD5009A.pdf

I wouldn't bother trying to install 2.003. It is obselete and if you've lived with it this long - you don't need it. Instead, update to the 2017 firmware and maps.

On my Z110-BT it is in /USER/SETUP/BT. Here's mine but I don't know if it will work. Did you try just copy/deleting yours and see it it could be recreated? BTUNIT.DAT

First make sure that your parking brake is detected as set. Go to Settings / Navi Settings / Connection Status and make sure it says Parking Brake is On. When Off, some settings and functions are grayed.

I think there might be a few minor differences in the menus. Did you also update the Bluetooth to v3.32? I can't help with speed cameras. I think somewhere in this thread someone posted about that. We don't have that "feature" in the US. I assume your iPod is wired and your Samsung is through BT. If you are trying to use Pandora or Aha, there is a setting somewhere called App Connection" where you select wired or wireless (BT). iPods should be wired (USB) with the proper cable. Some people have reported problems with Samsung via BT. But whenever there are problems after a major update I recommend to do a cold-start by disconnecting the battery for a few minutes.
