MKIII ejecting map disc on my MG-ZT
 

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

nobody knows if you can upgrade the OS on a Rover Factory Fitted MKIII Satnav?

what version is fitted now?

it has been around 6-8 years since the last range rover OS update, you might already have the latest OS loaded.

and if the map is ejecting you might have a dead laser in the mkiii

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

You don't need a map disc to check the OS version

Look on the top right of the Settings screen, there is displays the OS version number.

anyway the OS version is irrelevant i dont care about upgrading i just want to reload the OS software

Not really. There is no point reloading the OS if you already have the latest version

You achieve nothing in a very risky way. You can kill the Mk3 if you create a OS disc in the wrong format

Hence I repeat: if you already have the latest version loaded, do not touch it!

One more: what version is loaded now?

Jack dump the mk3 and buy a mk4, then install the latest OS with the splash changed to rover (there are a few on here).

Can you suggest any suppliers / indicate cost?

Thanks
