Yes. These wireless adapters can work with any TI-Navigator system.
The CX wireless Wi-Fi adapters are designed to work with any TI-Navigator system. While the TI-Navigator software will remember any network adapter that has been associated with it, you can remove that association and re-associate the adapter with a different Navigator system when needed. This is true for adapters that come with a full navigator system or if they are purchased as a 10-user add-on.
