开机后，如果LED灯慢闪（闪烁周期为240ms），为AFHDS系统。
开机后，如果LED先快闪2下，再慢闪一下，快闪周期为240ms，慢闪周期为720ms，总周期为（240ms*2+
720ms＝1.2S）即为AFHDS2A系统。
Turn on the radio. It is AFHDS system if the LED keeps flashing (flashing cycle is 240ms)
Turn on the radio. The LED flashed quickly twice, and then flashed slowly once. In addition, the quick flash cycle is
240ms, and slow flash cycle is 720ms, and the total cycle is 1.2S(240ms*2+720ms＝1.2S).If so, the current system is
AFHDS2 system.
Switching system between system AFHDS and system AFHDS2
The current system will be switched by another one when
turning the steering wheel clockwise or counterclockwise to the
end and then turning on the radio. After that, restart the radio to
enter work status.
