Land Cruiser Satnav Head Unit

[sotal]

A friend of mine has had a Big Land Cruiser 07 reg as a courtesy car whilst his car was being mended.

It's got the Satnav Headunit in but it's not folding up properly.

Initially he pressed the open button, the screen folded down, he put a CD in and it closed back up again, played the CD fine etc, but then when he came to open it again to get the CD out the screen got stuck half way down, after a bit of playing with it (and forcing it a bit) he managed to get it low enough and the CD came out.

but now the screen doesn't shut properly at the top.

Is there any way to fix it as the hire company are picking it up today!
