The "From Last Destinations" option in my car's Navigation system suddenly stopped working a few moths ago. Instead of displaying the last few destinations I entered into my GPS, it is either greyed out, or the only destination in the menu is one that I entered over four months ago, before it stopped working. The "Last States/Provinces" option under "Address Entry" does not work either. The rest of the navigation system works perfectly.

Has anyone else had this problem or know how to fix it? Thanks?
