Hi there,
Do you have the MMCS manual that comes with the car?
Don't forget to also remove your "home" from the Navigation system...
The previous owner of my car forgot to do that.
From the MMCS manual for my car:
To delete a frequently Used Location:
1. Press the NAV|MENU key
2. Touch [Personal]
3. Touch [Delete] in "Special Location"
4. Touch the "frequently used location" to delete
5. Touch [Done]
6. Touch [Yes]
To delete an address from the Address Book:
1. Press the NAV|MENU key
2. Touch [Personal]
3. Touch [Delete] in "Address Book"
4. Touch the "address" in the "Address Book" to delete
(Note you can 'Select all' at this step if you wish)
5. Touch [Done]
6. Touch [Yes]
Deleting a Phone Book:
1. Press the INFO key or touch [Mobile Phone]
2. Touch ^ (up arrow) and then [Phone Book]

To unregister all devices from the system, you should follow the online deregistration steps.
