The Prambanan's coordinates are slightly off.
Here's my version:

http://maps.google.com/maps?ll=-7.752056,110.492077&spn=0.079823,0.13114...

The complex is at the riverside and quite closed to main road connecting Solo and Jogja. On the lower-left, you can see Jogja's airport strip.

Even at this zoom level - you can see the temple complex.
