Anyone have any experience using the navigation wake up disc? I was given the disc by a member on this site but not sure how to use it. I put the disc into the cd changer and let it play. It played for a few minutes with no sound then continued on to the next disc in the changer. Am I missing something? Maybe a trick in using the disc? I am trying to wake up my nav after having a failed update happen. The drive worked perfectly fine until I had burned copy of the updated map dvd in the drive and an update fail. Now the head unit doesn't recognize that the nav drive is present. I tried doing a hard reset by touching positive to negative battery cables but didn't help. My car went through the idle calibration so I know the reset was a success. Any help is much appreciated!
