Is there any way round this, as I want perspective mode but it's not giving me the option at all.
Confirm boot mode using NavCoder.
What does the nav report?

Then do a downgrade to an old version like V21 or so, then upgrade again to V31

If boot mode is already set to BMWC01S, you won't need to change boot mode.
