Nav active while driving code?

[drivesafe]

OK this is a Range Rover question but hopefully someone here might know the code.

The code to activate the Nav address entry feature while driving is 1791.

Unfortunately this does not seem to work on my RR.

Anybody got any clues as to what the RR code is?

Hello Tim

The ability to use the diag pin was removed as part of a firmware update. Seems LR cottoned onto folks unlocking nav on the move and stopped it.

You will need to have either the dealer do it or get a faultmate and fix it that way.
