Hey all,
Haven't been on for a while. Moved to the UK in 2015 and brought the car with us. Bought Western Europe maps on DVD cheap when we got here, like £30 for the latest at the time, works perfectly....however.......We're about to head back to Sydney, shipping the car in 2 weeks and had a look for a map update to switch back to Australian maps.... Holy 5h1t!!
Has anyone got some advise on the best way to go about it? The cheapest I can see for the latest version is $550 which is crazy! I'd be tempted to swap out for an Android head unit before doing that to be honest. Would prefer to keep the factory look though.

Details: Octavia 1Z MY11, Columbus RNS510

Any help/advise on the path to take would be appreciated.
