The drawback of this is that you can only search in the area you have saved on the map, if you have gone out of the saved area then you will no longer receive the correct instructions.
Ideally, save your offline map area a little wider and, if possible, save additional areas, areas that you will pass through.
Note: The downloaded offline map can be used within 29 days, after this time, the data will be automatically deleted and you must perform the download again.
Hopefully, the steps of using Google Maps without wasting space will help you use the map effectively.
Hope you are succesful.
