How Link membership renews
Year 1 is included from first activation. After that, renew the adapter you already own — the hardware stays in the cab.
12 months from first activation
A new Link includes year 1. The clock starts the day you first activate the device, not the ship date.
The adapter stays yours
When membership expires, hardware stays in the cab. Regen, live data, bidirectional commands, and updates pause. Cloud history remains saved.
Auto-renewal only
Renew the adapter you already own with monthly, annual, or 3-year billing. New buyers should purchase the hardware first — year 1 membership is included.
