Hi, I have a GS300 on a 1995 model. I have stored the car for the winter and left the door open. I now find that a code has been entered into the radio and I cannot now get past the "sec" code entry system. I know there is a procedure to reset the code, but as I used to work in the local dealer and now have started a garage of my own nearby I am not very welcome there. Anyone know how to do it? Thanks
