Afternoon all,

I recently purchased an MG ZT complete with the MKIII SatNav (which I have been lead to believe is the same as those installed within BMWs).

When I power on the SatNav the map disc ejects.

Before buying a new Map Disc as this may be the problem I figured I would try to update the OS/Software/Firmware or whatever its called!

Firstly can this be done on an MG fitted MKIII as I have read a few posts saying that the Firmware gets locked?

Secondly if this can be done which version should I update to and is there a good step by step guide available?

Many thanks in adavnce,

Jackyboy
