NOVELTY - The method involves receiving a first signal from a vehicle (105) at a mobile device (120), the first signal identifying a location of the vehicle. A current location of the mobile device is determined. Determination is made whether a location criterion is met and the determination is based on the current location of the mobile device. A second signal is transmitted to the vehicle in the event that the location criterion is met. The second signal includes an instruction to control a function of the vehicle.    USE - Method for communicating between mobile device such as phone and vehicle such as car. Can also be used in mobile computing device such as laptop computer, tablet device, multifunction device, mobile phone, portable gaming device, portable multimedia player, portable music player, personal digital assistant (PDA), portable electronic and electro-mechanical device, ipod (RTM: Portable music player manufactured by Apple), iPhone (RTM: internet and multimedia enabled smart phone), and iPad (RTM: Tablet computer developed by Apple) device and vehicles such as commercial and non-commercial vehicle such as truck and sports utility vehicle, gasoline-powered vehicle, electric vehicle, solar-powered vehicle and hybrid vehicle.    ADVANTAGE - The accessory can control or coordinate control vehicle functions in response to receipt of the second signal hence the vehicle operator can passively and efficiently control feature operations of a vehicle. The mobile phone can generate and transmit a second signal to the vehicle accessory identifying the function control to be implemented, upon detecting a particular location criterion.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a mobile device for communicating with a vehicle;    (2) a method for controlling vehicle functions; and    (3) a device for controlling vehicle functions.
