Kenwood head unit issue

I have a Kenwood ddx40(18? I think) model head unit

I have just had a few issues this week with it. I pulled the alt s fuse the other day to see if it was the diode model for a dual battery system. Ever since the head unit has been powering up as if it has had all power cut to it. Screen scrolls through the features slide and all presets and clock are reset. Everything else is fine and the fuse is the only thing I have touched.

Anyone else had a similar issue?

Cheers

Forgot to add...

The main window switch on the driver's door had an issue at the same time but seems to have sorted itself.

The light on the driver's window switch was flashing and the auto function for the driver's window wasn't working, but seems to be sorted now

Was the car running when you pulled the fuse?

No. Had been off overnight.

Don't know about your head unit. But, your windows need resetting.
When you disconnect power, either battery or fuse, your auto window switches need to be reset. You'll have to reset all the auto switches one buy one from each position in the car (Not from the main controller except for the driver of course)
To do this, you need to repeat this procedure for each switch on each door for each flashing switch.
Start with your driver door: Start with the window all the way up and in one press, hold the drivers window switch down and hold till it is all the way down, then hold the switch up until it closes all the way again and then the light should turn solid to indicate that it has reset. If it is still flashing, repeat the process. The work your way around the car to each door and do the same for the other.
