Purchased a 2010 Acadia in 2010. Activated the free 3 month trial. It was active for 5 years! Finally went out and after a few months I was able to activate a 2 month free trial on the same vehicle. Just bought a 2012 Enclave and activated the trial.....they tried to up sell a year's Premium sub at $10/mo but we told them we will see how we like the trial....Maybe they will call back in 5 years!
