Radio Station Scan

Love the Road Glide and love listening to the radio when riding locally. When on a trip I listen to a mix CD that my wife made me with about 8 hours of music on it. The problem is I would like to be able to scan through the memory settings of the different radio stations via the hand controls insted of just the reqular scan which just stops on the next station it finds. Even with me being tall with long arms it is a pain and destracting to lean up and hit the preset memory buttons.

Is there anyway to change the scan on the hand controls to just scan through the memory settings?

If not was thinking about replacing the stock radio later. Is there an aftermarket radio/hand control unit that would do this?

Thanks for the help.
