I have a 2012 Toyota Prius. The car was directly imported from Japan by the previous owner. So it has a multimedia system which was fixed in Japan. It includes 2 nos of memory card slots, one for “music” and other for “maps”. My questions are, 1. Can I use this as the navigation system in Sri Lanka by simply downloading the map into a memory card and installing it? 2. Where can I find to purchase the relavant maps? Have attached some photos of the inner interface. Thanks in advance.
