This may help:Hiya
im brought my rs from Australia to the uk but it’s got no uk maps on it ( factory loaded Australia maps still on it ) so i was hoping that someone could tell me how to change the region on the APIM to uk Europe so I can load uk maps
A guide on updating your Ford Sync 3 based car to the latest Sync 3.4 version, now with the latest F9 / 1.19 maps. Supported regions : Europe, America, Australia, New Zealand, South Africa, Middle East, India, South East Asia, Israel, Turkey, Central America, China and more!
There are region changing instructions there. IIRC it's a little more involved than changing the region, but if you know something different please share!
