Installed a Kenwood KDC-MP146 and each time i turn off the car ignition I have to reset the stations, clock and cancel the demo mode. Is this a wiring problem and have i incorrectly connected the system?

its in the menu setting under demo on /off put to off.

also to add if you have to rest the time every time then there is no continuous power to the unit if you have to do the time all the time when you turn it on the unit needs 2 lives on continuous and on switched, switched is from the ignition and will only power on the unit if the key is turned continuous power is to save settings has to be on permanent live connection to the battery fused.

You should rewire it, if i remember correctly yellow wire should be connected to constant + (or directly to battery +) so the radio doesn't lose any settings when you turn it off

Follow the instructions on page 12 of the manual.

Firstcheck whether it is still in demo mode. to cancel demo mode -- press [enter]when message flashes "to cancel DEMO mode press ENTER key" for 10-15 secs. Turn the control knob to "YES" and press ENTER key. If it still fails to operate properly press the rest button to return to factory settings(The reset button is behind the front console)

go into the menu. you should be able to scroll through the menu and turn demo off.

press menu till it shows demo, turn dial it should flip "demo o" demo off"

I spent the better part of an hour trying to figure out how to get the "Clk Adj" screen on the KDC-MP228. Here is the solution (dont waste your time reading the manual, it does not explain this). First, I had screwed up my settings so I did a factory reset (hold in the reset button). Then, you need to turn off Demo Mode (in standby click the Menu button and then use the control button to navigate to "Demo On". Hold the control button in to turn Demo on or off (this is different from all of the other controls in the manual). Now that Demo is off, click Menu button again and use the Control button to navigate through the options, one of which is "Clk Adj". At that point, you can follow the instructions in the manual (Hold in Control button until the clock blinks (approx 2 seconds), then use the FM/AM buttons to change the Hours and the << >> buttons to change the Minutes). Press the Control button again to save your changes. I cannot believe how difficult it was to set the clock on this device, someone should smack the developer who wrote that code.

Press the Source button until the unit enters Standby mode. Then press and hold the Menu button. Scrolling through the menu functions, you should come to one that says "demo". Turn it off by pressing and holding the 4-way knob.
