i have to start a project for control the FM radio by Remote Control,

information,plz help to me..

At the very least, one would need the type of receiver and the
microprocessor it uses to help you. For the actual work, both a service
manual for the former and a datasheet for the latter would be of use. An
example for a modification of a home FM tuner can be seen he

This is a bit more involved already. A number of tuners have proprietary
remote control inputs, which may also be worth a try provided one can
figure out (find) the accepted control codes.
