I purchased & downloaded EZcam for detecting radar. I don't know how to operate it. I can see green radar circle but no cameras detected. Do I need to put them manually? There is option for "Get database" for few of them such as pocketgpsdatabase or mapradar. But I have no clue how to get them Anybody using it, please help me. It is frustrating when there are so many free apps & I paid for this & cannot use.
