BTW to the OP: you can see history of the app on the package page.

I did a brief search for online radio station databases by lat/lon and couldn't find a free one. The most compehensive database might be this one: http://www.radio-locator.com, but to access lat/lon data requires licensing (i.e. paying). Without a freely-accessible database with lat/lon, how would the station download be implemented generally?

This link might be useful to those using the transmitter to broadcast to their auto stereo system.
