MY 2002 9-5 sat nav - broken touch screen glass [5521372]

[tophamn]

I've just acquired a 5521372 sat nav head unit - with a broken touchscreen. I've dismantled the unit and removed the smashed glass touchscreen but there are no marks, numbers or anything allowing me to track down and source a replacement.

Anyone know where I can get one? - or at least any information so I can track one down?

Many thanks.
