I note it doesn't fit cars with electric aerials. Is there a way I can know for sure whether my car has a manual aerial or just an electric aerial that has stopped working?

Have a look in the boot under the Ariel and if you see a big plastic housing attached to the bottom of the ariel then you have a broken electric one.
