Hi I'm having a problem with my battery just now and find that some mornings there is not enough juice to start the engine, (this is not a problem as I've ordered a new bettery) however when I do get it started I find that my radio needs the code put in, my previous vectra had a CCR500 radio which didn't ask for the code. Does anyone know how I can set up the CDR600 to do the same. Thanks Mark
