Looks like Infiniti has a pending solution for the 2G transition which we will hear more about this summer. You can imagine the profit stream they derive from the Inifiniti connections so expected they would figure something out ... and looks like shared cost to upgrade system. Info sent from Infiniti:
We are contacting you with an important update regarding how upcoming cellular network changes will impact your access to Infiniti Connection features in your 2016 Infiniti QX80. Depending upon your interest, this update may require you to take some action.
The Infiniti Connection features available on your vehicle will be affected by the planned discontinuation of the 2G cellular network by our service provider, AT&T. Specifically, after December 31, 2016, the 2G network will no longer be available and your vehicle will be unable to access Infiniti Connection features unless the telematics hardware in your vehicle is updated.
If you have not already enrolled, but are interested in doing so, please enroll as soon as possible - you must enroll in Infiniti Connection before June 30, 2016 to activate the service for utilization on the 2G network through December 31, 2016.**
If you choose to continue to subscribe to Infiniti Connection after the 2G network becomes unavailable, you will need to have the TCU in your vehicle updated to access the service. Infiniti plans to cover a substantial portion of the parts and labor costs to install the updated hardware. Infiniti expects to be able to communicate the details regarding the options to update your vehicle with the new hardware in late summer 2016.
Infiniti Connection provides a suite of convenience and concierge services that can help make your drive time more productive, convenient and secure with features such as Emergency Calling and Automatic Collision Notification. Other great features available include Remote Door Lock, Destination Assistance and Stolen Vehicle Locator.
Infiniti Connection helps keep you connected and provides peace of mind. Infiniti is committed to working with you to make this transition as seamless as possible. We look forward to staying connected with you through Infiniti Connection.
