For about 2 months ago my radio started requesting the safe code each time I have had stopped the engine. I enter the code and its ready again, but why? Sometimes, more and more often I also the the error: "Safe pin not connected" or similar. Then I press OK 1, 2 or 20 times (while waiting a couple of seconds each time) and the it starts. The car is a Ford Galaxy 03/2001 from Germany and the radio is the double din navigation system with cd-changer in the back. I wanted to remove the radio but cannot figure out how to do so. When removed, I wanted to test if the power is connected of a fuse is blown. Is there a battery build into the radio? anybody with instructions on how to remove the radio? Please let me have your comments. Thanks in advance. /John
