There is a remote services plan. Before Christmas I got an email with promotion that was $5/mo for remote start, remote lock/unlock, sound horn, and remote vehicle tracking.I don't have any trials or subscriptions. I'd like to try out for a couple of months the subscription where you can have remote start, etc.
I don't have nav, so the $10 nav plan wouldn't work. The other option is the assistance plan for $15. Of course when I hit buy now, I got "oops something went wrong try again call 1800"
