Almost certainly. Google maps are downloaded as you use them, unless you've specifically downloaded them and saved the areas you need in advance (and then they only last for 30 days ISTR).

SD charting data is downloaded in its entirety country by country, as are the plates if you want to save them. You will need a wifi connection to do this (as you will for any updates, NOTAM and weather just before you fly).
