Systems and methods for handover of activities between a vehicle and a wearable device involve pairing the wearable device and a vehicle device with a wireless telephone. The proximity of the wearable device and the intention of a wearer of the device are determined and used to transfer information between the wireless telephone and the wearable device and/or the vehicle device in a seamless manner. Depending upon whether the wearer is in the vehicle or outside of the vehicle an activity, such as navigation, will be performed either by the vehicle device or the wearable device.
