I bought one of this with 200mm x 100mm space:

And one Parrot Asteroid Smart
http://www.parrot.com/au/products/asteroid-range/parrot-asteroid-smart, basically to use it as a gps.
The thing is the asteroid has a standard double din dimension, which is 180mm x 100mm.
My car is a Subaru Liberty 2005 Premium Pack.
Any idea how to fill the gap? I live in Melbourne.
Thanks in advance
