Yup

Yes its true, you would need to re-code your system if you ever loose power. You should have received a credit card size card with the code on it to save for just such an event. You can get the code from your local dealer but will be needing to show proof you are the owner. IE , registration etc.
Good luck - at least you have time to find out now while your radio is working. Rod
