New York - SiriusXM expanded its efforts to get used-car buyers to activate their factory satellite radio.

The satellite broadcaster announced that participating Nissan and Infiniti dealers will be able to offer a free three-month trial subscription to consumers who buy any used vehicle from the dealers' lots, not just Nissans or Infiniti.

 Sirius XM launched a similar program in June with participating GM dealers.

The satellite-radio broadcaster also offers trial subscriptions to consumers who buy certified pre-owned vehicles from such automakers as BMW, Mercedes and Volkswagen.
