JVC car stereo keeps switching demo on after I take the key from ignition.?

Bought a nice little JVC head unit (JVC KD-R601) for the car, from halfords (an x-demo one, great bargain), so it keeps switching into demo mode every time I take the keys from my ignition.

So what I've done:
installed the head unit, tested it, all good.
noticed the demo mode, switched it off (in the menu->demo->set demo off), the demo mode turns off and everything is ok. once I power off the engine, take the key out of the ignition and put them back in, the demo is back on.

This is annoying the nuts out of me and google does not seem to be very helpful.

Would appreciate any advice.
