The headunit can be switched on without key in ignition as it has a permanent feed.
Either a wiring issue or faulty unit.


But thinking about it, I reckon it could have had an aftermarket head unit fitted, and someone may have swapped the permanent and ignition feed around.

Does the unit turn on automatically with ignition.

Remove the headunit and check the permanent and ignition feeds. Usually red and yellow. If they have been swapped, for when installing an aftermarket radio, then this will be the cause. It should be obvious to spot one head unit is out.

Does it keep time, and radio stations?

Sounds like headunit is just faulty. They can get warm and shut off.
