SB Radio FW 7.5.1 r9009
SB touch FW 7.5.1 r8837

Usually the radio is synchronized with the touch, but many times after resuming playback the two are 'horribly' out of sync. Sometimes a few milliseconds, sometimes like being unsynchronized. What I then usually do is got the synchronize menu and unsynchronize and resynchronize the two, sometimes once, sometimes several times to get them in proper synchronizity.
Proposal:
when the two SB are synchronized, the synchronized SB is marked, so I can not select this command in the menu anymore, instead I have to unsynchronize and resynchronize. In a situation like mine it would be beneficial if I could just re-perform the synchronization command, so the two SB get in synch. This would mean the synchronization is performed regardless of the selection shown. So even the radio is already synchronized with the touch and also shown like this in the menu item, pressing the touch again initiates the synchronization process again.

In my opinion this would not cause any confusion, as if I get into the menu unintentionally, I leave the menu with the back or home button, if I press the the item to be synchronized with it just resyncs, if it has not been sync'd before, it will be synchronized. It would just help in situations where the synchronization process was not so perfect and a resyncing is necessary.
