Hello & Welcome to Just Answer,
Sorry to hear of any issue you are having with your device.
To help you with this issue, may I ask:
1) WHEN was the device last SUCCESSFULLY used?
2) HOW are you "looking for" the Europe maps (looking at main map screen or some other screen)?
3) Can you confirm that the Europe maps are stored on a memory card AND that card is inserting in the device?
