If there is water in the screen of Garmin this is nothing to worry about as the user can easily get the water removed for that fill a zip lock bag with raw rice put your Garmin inside the bag for 3 days and leave it the rice will throw the water out and it will again get restarted. Another trick that can fix this problem is to remove rubber from the buttons and allow it to dry and the issue will be fixed. I hope this gives an answer to the problem you are dealing with and for any technical support visit at Garmin Helpline Number & http://www.garmincustomerservice.co.uk/
