The security point is spot on but dont forget that our criminal fraternity are most likely to go for what they know , understand and can see.
A top spec tom tom mount they will smell at 500m , a universal type mount quite interesting but " a bit of metal and a wire hanging down" duh whats that ?
They almost always nick to sell so whilst I'm not saying its a bad idea to hide things away they will always go for something useful, to be useful its got to be identified, hence the obvious dont leave laptops and sat navs in sight.
They are also likely to break into a car for a nosey in closed compartments if pushed especially if there's any give away sucker marks on the window or a Krussel type plate fastened somwhere.
The point there is that if the mount is hidden somewhere in the car its likely the kit attached to it is too.
If they want it or even want to look for it on a whim your car will get screwed anyway. Theres very few cars dont contain nickable items.There was a lot of research put into those ads telling you to remove everything from your car to be safest.
Its a cruel world but dont let paranoia spoil it, just avoid being an obvious or easy target :thumbs
