Removed radio to try to find code after flat battery I got code from manuafacturer replaced radio found clock in dash had stopped working Thought a fuse may have gone checked fuses now every time ignition is turned off I need to re input code and retune stations. Does any one know where the permanent 12V fuse is located I can only think Ive put it in the wrong place. Also I didnot touch the clock so I would like any thoughts on tha too.
