Is there a special mode the RRS can be put into - to access special functions for diagnosis, or debugging?

Thanks,

I am sure there is, I have been with lexus for years and every time a new generation of nav systems came out someone always knew someone that worked at service and told them how to get to the diagnostics screen. Some of the settings ended up being really usefull like using the navigation while driving. Maybe one of us can find a contact at land rover service to see if they will tell us how to get there. I will try once my car arrives.

There is a test/diag mode for the Touchscreen, but there is nothing that you can "change." Fairly boring.

For the full vehicle... sorry, that's what real diagnostic systems are for.
