The preinstalled FM radio app can not be changed, sorry about this, and it does not matter with the FM radio play.
Actually the FM radio may be affected by the surrounding interference and the aftermarket FM radio can hardly perform as perfect as the original one.
Please first check if the radio antenna has a blue single wire which need to connect to the 12V power line, then the FM radio can get the stable FM signal. And you can also use a FM radio booster to improve the FM radio signal reception.
