Hello community! First of all thanks for this awesome application! When I use the FM-Radio and finally close the calling, one can hear the "transmitter is on" beeping and after 15-20 seconds of silence the transmitter turns off and one can hear the scratchy sound of a unused radio frequency. Can I disable the annoying beep AND the automatic transmitter turning off after while of silence (fm transmitter shall be active as long as fm-carkit is running)? If yes, how? Furthermore I am using the Brodit carmount, the phone is placed in the middle of the car, above the air vent frame. When driving faster the noise is pretty loud, the dialogue partner can't hear me talking. I installed the modified "fmtdx" of jacekowski.org, which permantly sets the FM power to 120 and makes the FM-transmitter work independent from a plugged headphone or charger. My hope was, that the microphone of the headphone is used, when fm carkit is on and the headphone is plugged. The microphone could be installed to the sun visor and be directly in front of me -> clear sound even at noisy speed. I made a test calling to find out whether the the headphones microphone is used or the built in microphone. Unfortunately it is the built in one. My suggestion: It would seriously be useful, when the FM Carkit detects whether a headphone is plugged in or not. If a headphone is plugged, the phone should use the headphone microphone and if it is not plugged the standard built in micro. Summary: A possibility to disable the "beeping" + "transmitter auto turn off" and the headphone microphone functionality could make this application perfect! best regards redhotfoo
