vauxhall astra problem

[mboman]

on the center consol obove the radio there is a display it does time date and outside temp, now for some reason
when i turn the radio off and remove the ignition key ,the time and temp lcd stays on and the electric arial stays up what is the cause of this !!!!

thanks 4 that, anyway it is the radio doing it i asked a masterfit mechanic. but a new unit costs more than the car is worth so it will have to stay like it !!!!!!!!!!!!!
