Limitations
There are some limitations to the functionality of the offline maps, mostly regarding the size of the location you’re looking for. For example, New Delhi and surrounding areas would be a bit too much for just one cached file and you will receive a message saying it can't be saved. In this scenario, it would need to be broken into smaller, surrounding areas. Also, offline navigation is not available, nor is the ability to conduct a search within the offline map file. The maps you download will be stored for thirty days and after this they are automatically deleted, so don't presume they will last forever.
