Rose FM Location Setting

I live in San Diego, California.

I have set my Rose FM location as the US, however the location options for FM radio stations that it shows in the pull down list is Santa Monica, more than 100 miles away.

How do I get Rose FM to recognize I am in San Diego and then allow me to listen to my local San Diego FM broadcast stations?

Thanks
Mark

RoseFM is not something you listen to by connecting to a frequency.
We customized the app by adding several radio channels to each frequency.
Currently, development of the RoseFM app has been discontinued.

We apologize for any inconvenience caused.
