Driving from the airport to Icmeler

I am going to Icmeler in 2 weeks and are thinking about hiring a car and driving from the airport. Never driven in Turkey before and as it is a late flight I would be driving in the dark. Also, are satnavs reliable there, I was thinking of downloading a turkey map and using it in the hire car. What do you think ? Am I going to get to Icmeler or will I spend the night touring the Turkish countryside ?? Thanks.
