Nav help

Anyone know how or where to get an update disc for the navigation system?
I really do not want to spend $200.00 to update from 07 to 12. I was hoping it was like my garmin , you could buy an update for $75.00
Thanks!

any version as long as they work in my truck I would be willing to purchase from you.
