I'm sorry, this is probably a dumb question that has allready been asked:

Is it possible to listen to the unit without the car being turned on? I'm aware this may vary from car to car (I think the new VW bug can do it, but I'd never get one of those). I only ask because I've seen hints of it in other posts.

Thanks for your help.

Its just a case of linking the power so it isn't dependent on the ignition.
