Solution 28210: Updating a Calculator Operating System with TI-Navigator™ System.

Can I update my calculator operating system using the TI-Navigator system?

It is possible to update the operating system of the TI-73 family using the TI-Navigator system.

The nature of the TI-83 Plus family and TI-84 Plus family operating systems requires these calculators' operating systems to be updated manually.

The TI-Nspire in TI-84 Plus mode has its operating system updated when the TI-Nspire operating system is updated. It cannot be updated independently of the TI-Nspire operating system, and cannot be updating using the TI-Navigator system.
