OBD freezed codes??? what the???

when i scan codes, it sez no codes found, something like that. but theres a button where you can select freezed codes. huh? when i pressed it there were tons of codes!!!! AAAAAAHH!!!!! it was like i had every code available. any input on these?
you know how we have wireless keyboards and mouses that are read by the computer via some kind of device that is plugged into the USB and interacts with the wireless device?
how cool would it be to have such a device in the car to use with the GPS, radar detector, and OBDII gauge? kinda far-fetched right now, but i like the idea....get rid of all the cords
