stations

I have searched through the manuals and cannot find an answer for this: how do I delete preset radio stations I no longer listen to? In some cases I accidentally preset the same station two or three times. Also, is it possible to change the order of preset radio stations on my Technology...

Does anyone know if and/or how to delete stored stations from the FM, AM and XM menus? I went to select a station and discovered someone (wife????) had stored the same stations multiple times. Now I am stuck with 30 stored stations rather than the original 6 station we agreed upon. Thanks:(...
