In 2 years of no use it could've got damp inside and broken tbh.  Bit of a long shot but do you know anyone else with a Mk7 Fiesta that could borrow their radio to test?

Also have you definitely pressed the on button?  It's the volume knob on them iirc.

Ok, well it's obviously getting power so it sounds like a fault with the unit itself.

Does anything happen if you try to select an input like radio or CD?

 If I press CD  it says no CD in drive!, only  thing that comes up on the screen

Ok, and nothing when you press radio?  I can only assume it's an internal fault that isn't really fixable unless you're into electronics.  If it was mine I'd change the radio unit, I doubt they're cheap for those though.  Maybe someone else has a better idea.

Sounds like a security measure may have tripped due to the system thinking the radio had been removed.

Maybe a trip to your Ford dealership to reset it would be in order?

Try disconnecting the positive connection from the battery, touch it to the earth terminal or bare metal part in the engine bay (to discharge residual charge on the system) and then leave disconnected for about 10 minutes to reset the ECU.

See how you go from there.

When you charged the battery did you remove it from the car or leave it in place?

You may have fried the unit.

I would replace the radio fuse just in case even if it looks ok, may be the ignition live feed is disrupted and causing the problem.

Failing that your dealership will have to look at it properly.

ive seen that before, and it was the display unit that was faulty, not saying that is whats wrong with yours though, the dispkay wouldnt communicate with the audio unit. first person to diagnose it thought it was the audio unit, then i went to fit unit and it still wouldnt work, so i borrowed a display and it worked again. could either in your case unfortunatly.

Definitely a strange one.

Is the battery up to full charge and/or holding a charge?

It may stem from the battery being dead for so long, it may have gone below a point where charging it is not enough for the car systems to run properly.

I'd get a battery health check done and see if that sheds light on things.

What happens if you put a CD in? You said if you press the CD button it says no disc but is there actually one in it? It might play if you load one in but not display the track etc.
