Does anyone know if these units can be repaired ?

The one on our saloon has fallen off and thus seems to have damaged the on/off switch...

Can it be repaired ?

I've opened it up and can see the damage to the little micro switch and wondered can it be re-wired to an external on/off switch, as a new one is pretty expensive lol

 

Does a AVCR even have an on/off switch.
I have black one in my car now without one, and have had a silver one before without one as well.They both had the 2 buttons on the right, and the 4 in a cross pattern above those

 

Mines an older model which was fitted in japan. It has an on/off switch on the right digital display in the middle and then a volume button & mode button on the left side
