Welcome to the forum and congratulations with your new(-ish) B&O product
As far as I know, there shouldn't be any problems exept that the older ipods charges its battery on one of the other "pins" in the connection plug. Try to wiggle the ipod in the connection plug, or see if there is dust and dirt in the plug of your ipod (just like the old Nintendo cartrigdes!)
