Very nice radio app. Worthy every penny. Keep up good work.
But I have one annoying problem. it seems to me that the radio does not switch between frequencies (AF).
The already installed radio app was switching between frequencies (this android head unit), at least it seems to me. This app doesnt want to. I saved frequencies in one station.
The problem also arises in some areas when I'm driving, as if it wants to change the frequency, I can hear other stations for a couple of seconds, or up to 15 seconds. What can I do with this? its pretty anoying. Beacuse that came up every 10 minutes of driving...
Where to look and adjust the AF to make it work as it should. The built-in radio worked better (car radio came with car). I do 200km a day and have to switch 3 frequencies. In stock radio workd well...
I also bought an antenna amplifier. My car is Passat B7
With the new update, I noticed that when I move through the stations with the buttons on the steering wheel, it just skips the station or goes back to the beginning...
And one more thing when I disabled stock android head radio app. NavRadio doesnt boots up at start. And I have selected boot up at start...
The RDS AF function allow the radio tuner to tune in to an alternative frequency when the signal becomes too weak.
On normal car stereos this function use 2 PLL receivers to hold the old frequency until a new one is found y the second PLL.
On all Chinese units it's used just one PLL and the function is controlled by MCU and radio chip it self. So when a station become too weak you will notice a frequency scan that will look for another frequency with same station RDS ID code. The scan quality depend on many factors and none of the Chinese units have implemented this function correctly.
Only the MTC device handle it a bit better than others.
On FYT units the AF functions is totally wrong and should turned off.
NavRadio can only switch AF "ON" or "OFF", It cannot improve this function because, as i said,it's handled by MCU.
Anyway NavRadio can help a bit the users storing the Alternative Frequencies manually: dragging the frequency from middle of the screen and dropping it on to a station button.
You can save up to 9 alternative frequencies and they can ve selected in the EDIT window or switch between them double clicking on the station button or sliding up/down in the middle of the screen.
