Hi All,

Been having trouble with my DVD drive failing to read the disk - occasionally get 'Not a Navigation DVD' message as well.

Decided to pop the drive out to clean the lens (worth a go on old cars) and realised it didn't have any bolts holding it in the carrier (which is worrying in itself)

Does anyone know if they are M4 or M5?

I know its a rubbish satnav as now 7 years out of date, but I do like stuff to work if I can.

Thanks for any help  Some days its just not worth chewing through the restraints.....
