Having just replaced my 01 Grand Voyager with an 05 its got the combined SAT NAV / Radio. But no Manual, how do I tune this in and get the station to stay on a button

 

Push SET/RND, then push a number to which you want to store the station.

To "seek" the radio stations, press the "forward" or "back" button in the bottom left.

Hope this helps.

P.S. There are actually 18 Presets. FM1 which has 6 FM2 which has the second 6 and AM has 6
