Check your Wiring, as it sounds like your Constant +12 volt wire is connected to the Switched +12 volt wire. This would cause all settings to return to factory, just like when you lose power due to a bad battery or battery disconnect. Since you switched off Demo mode, and it comes back, this has to be a wiring problem, or a defective unit, but more than likely a wiring problem. On most pioneer units, the Yellow wire is the Constant 12 Volt (battery) and the Red wire is the Accessory 12 volt (switched).

I have a jvc kd-r45 it will not recall any pre set radio stations after it is switched off and demo mode kicks in every time i start it up. Tried reset any ideas?


I don't think you have the memory keep alive wire attached to a constant 12V+ source. This is why it is not keeping set stations and reverting back to demo more every time it is switched on. Usually the memory keep alive wire is yellow.

My unit returns to demo mode everytime I restart my Chevy s-10 and I loos all the presets and clock settings


Make sure the yellow wire is going to a source that has 12v going to it when the key is turned off. The yellow wire controls the memory and needs a constant voltage source.

Pioneer DEH-P4000UB not turning off.


I thought the same thing but what is happening is when it turns off it is in demo mode and it looks like it's not off. When you hold in src it changes to something that says "USB/IPOD.. " scrolling. Press display and it turns demo mode off. Then it will turn on and off properly.

Stuck in demo


I had the same issue and was about to give up.
cleaning, key combos and such didn't work out.

Solved the dirty way, as described some comments above:

"Just took the faceplate from the "push-menu" button and hit it against a hard surface [not too hard but not too soft hits] and thats it, it worked again."

ah, the good manners!

Kenwood KDC-MP635 STUCK IN DEMO MODE


Turn the unit onto standby then press and hold the menu button then scroll down to demo using the toggle switch on the right then press and hold the toggle switch for a few seconds and it will change to demo off. It's not too difficult but you are correct, it doesn't tell you correctly in the installation instructions.

DEH-P670MP Display goes from regular to extra bright, then back


Your deck has "reverse mode" activated. To turn it off, just turn off the power by holding the source button. The press the preset "5" button. When you turn the deck back on, reverse mode should be disabled. (If this doesn't work, try the same procedure with button "6". One's for reverse mode, the other for demo mode, but I'm not sure I remember which is which).
