Hi guys, thanks for your suggestions.
I can't believe how easy it has been to destroy this unit!
Would either of you have, or be able to point me in the right direction for burning instructions on a Mac?

autotronic - how much does sending this sat-nav unit to you for a re-flash cost? Also, would it then be back to a factory firmware version, or are you able to install the latest version so i could again have the 3D viewing option?

Thanks again guys...
