Alright so I have a Z110BT that I have upgraded to the Z120BT software. I noticed there are 2 more updates out, the CNSD-210FM as well as the 2012 NAVTEQ map upgrade. Will I need to buy both of these to get my unit up to date? I was told by 2 sales people at pioneer to just buy the NAVTEQ and I will have all the stuff from the previous update as well, but then I was also told by a customer support person that I would need to buy both. Can anyone confirm that just buying the NAVTEQ update will bring me up to date on everything? Has anyone skipped over the CNSD-210FM update and just installed the NAVTEQ update?

No - you only need to buy the 2012 update from navigation.com - just be sure to pick the right one for your unit (Z110BT) - it will update it to the latest maps and software.
