I specifically requested that it be written in the sales paperwork as part of the complete sale. Well after repeatedly calling the dealership I purchased it from they said for me to bring it in . They had the disk. After bout an hour and half wait time. I saw it sitting there. They said No its not ready yet. You must wait a half hour. We had to disconnect the battery for 30 minutes. I then find out that they removed my unit and replaced it with another unit. From what I could bring up, either the unit or the CD or both are from 1997. Well needless to say, its.still working. In looking for info on obtaining a 4 digit sec code to reset. Any suggestions?
