Backing up stored addresses in the Amundsen?

Morning all,

After trolling through here trying to find someone who'd had the same issue as me, that is, how the hell do you find the place to input a post code when entering an address! Well, found that and will try later this morning.

However, does anybody know if it's possible to back up saved addresses? After I installed the latest maps (ECE2016), I seem to have lost my stored destinations: fortunately, they're weren't many of them! On my previous system there was an option to save stored addresses to a memory card/USB drive so all was not lost, but can't find this option anywhere in the menu, so I'm assuming it's a 'no go'?
