Hi nickmoo...,
As Fred says the software is too old to update via Web Upgrade and requires either a new programmed SD Card (available from our online shop) or for the card to be re-flashed.
I assume the SD Card, which holds the operating software, is the 'external' type that protrudes from a slot on the RHS of the unit. If you cannot see the card, as described, then it will be an 'internal' micro SD. You need to state the type when ordering.
