Did you ever consider paying a lot of money for an exciting trip around the Earth? It really makes no sense... just play Google Earth!
The cache is not at the given coordinates. Here's the game: use the street view function of Google Maps and locate the following pictures. For each picture you will have to perform a simple task in order to determine A, B, C, D, E and F.
Then go to
N 44° 28.(A+4)(B/10-1)(C+2)'
E 26° 05.(D/2-5)(E+2)(F+1)'
and search for the box.
1 - Catch exactly this image. As you enter the building, on the right window there is a three-digit number. A is the second digit.
2 - Turn around. B is the speed limit on this road.
3 - Again, turn around and you will see a number written in black. C is the first digit of that number.
4 - Look a bit to the right and check the greenish advertisement. They advise you to call a four-digit phone number for whatever reason. D is the sum of those four digits.
5 - A strange building, almost completely destroyed in December 1989. There are two hardly visible bulding numbers written on this side, on a small blue plate. E is the first of them.
6 - Continue along the street and check the GPL price. F is the first digit of that number.
All images were taken in December 2018. Google Street View may update in time but don't worry: you can still do it!
