time point t1 the step 30 of algorithm settings of fig2 is done already for these cars a b and c the server 52 and radio tuners of the cars a and b are then configured to communicate with each other as in the step 34 the car a and the car b optimizes or improves their radio tuners using data stored in their local radio tuner databases as shown in the step 44 these improved tuner parameters are later stored in their respective radio tuner local databases after this these tuner parameters are transferred from the radio tuner local databases to a radio tuner database of the server 52 as shown in the step 46 the transferred tuner parameters and other transferred tuner information are then verified as shown in the step 38 later data in the local radio tuner databases are transferred to the server radio tuner database as shown in the step 46 fig4 shows the implementation of fig3 at a later time point t2 which occurs after the time point t1 at the time point t2 radio tuner of the car c also tunes to the station s2 the server 52 detects that the cars a b and c are in the in.
