Patent ID: 8712404

Claim:
A system, comprising: a wireless interface disposed in a vehicle, the wireless interface monitoring a network for signals transmitted by cellular towers, the signals including a first system identification signal transmitted from a first cellular tower of the cellular towers; a computer processing device communicatively coupled to the wireless interface; and logic executable by the computer processing device, the logic configured to implement a method, the method comprising: receiving, via the wireless interface in response to the monitoring, the first system identification signal from the first cellular tower, the first system identification signal uniquely identifying the first cellular tower by a first system identification; retrieving a table of system identifications including the first system identification from a storage device, each of the system identifications mapped to a corresponding geographic location in which each of the cellular towers is disposed and a corresponding measurement system utilized in the geographic location; identifying the measurement system from which the first system identification is mapped; and displaying indicators of the measurement system within an instrument panel of the vehicle; comparing the measurement system implemented on the instrument panel of the vehicle to another measurement system that is mapped to a second system identification associated with a second cellular tower, the other measurement system being different than the measurement system implemented on the instrument panel; and in response to determining the measurement system implemented on the instrument panel is different than the other measurement system, prompting a user in the vehicle to authorize a switch from the measurement system implemented on the instrument panel to the other measurement system.
