Blue Link is about fun and it's about safety. Location sharing and hands-free texting lets you stay in touch with your friends while traffic updates help you find the best way to get to where you are going. You can also remotely lock your car, start your engine and if you've lost your car in the parking lot, you can even flicker the lights and honk the horn. Most importantly, and most impressively, the Blue Link SOS Emergency Assistance service can detect when you have been in a collision, locate your position and send the help you need.
