Hi guys, I was hoping you could help me. I've just purchased one of these little radios in the hope I can couple it with an arduino nano and then write a vb.net frontend so I can use it in my car. I have already wrote a vb.net / flash frontend which I give away free to all car pc geeks (like me :-) just search for 'FreeICE' and wanted to also get a rds fm radio. I've downloaded a Si4703 Lib for the Arduino and managed to get the little device working. I'm just wanting a few extra things. I need to be able to toggle the mute on/off the device and also extend the RDS reader. I would like it to auto-update the RDS by simply sending something like RDSNAME:xxxx / RDSDESC:xxxx down via Serial.println and my VB app would do the rest. Agian the signal strength and mono / stereo indicators would be hand. Either by asking the arduino or just auto receiving them. any help would be most welcome. :-) thanks, Steve
