it is a 2005 model MG ZT 4.6 V8.

Unfortunately can't check what version is currently running as when I put SatNav on it just says insert disc... Whenever we put the disc back in it just gets ejected again.. so as Kiwi says its possibly a dead laser?

Im not upgrading the version for more features I was just hoping it was corrupt or would somehow fix the ejecting CD by loading a new OS!

Let me know what you think,

many thanks
