searching blank radio station?
 

Hi all- I'm having some radio trouble. I had a cable installed in my '01 TT to plug in and play music from my iphone about 2-3yrs ago. It worked great. The problem is, the blank station I used is no longer blank. I have scanned and can not find any alternate blank stations. At the risk of sounding totally clueless, can anyone tell me how I can key in a specific station or browse one channel at a time??? I can't seem to do anything besides scan and that only picks up the channels that are playing music. Thanks- your help is greatly anticipated and appreciated.
