I have a stock 02 Grand Prix GT with the Bose radio system. The clock works when it decides I need to know what time it is or what radio station I am listening to, otherwise, it is blank. It appears that the clock is a seperate unit in the upper left corner of the face of the radio. Is it possible to pop it out and replace it? Or can someone tell me what wire I need to check to tighten up since it appears something is loose? Thanks in advance for any assistance. Bill
