After my day at LR Experience Eastnor, I've tryed to set up the tow assist on my car but I can't find the menu for manual settings (ie when no electrics are plug in as per the user manual).

I have the Surround Camera System with parking aid. As per the land rover website, this should include tow assist...

Extract from website:
Surround Camera System - five cameras. Includes Parking Aid - Rear View Camera. Includes Tow Assist (requires Rear View Camera)

Is it possible to have the surround camera without the tow assist? Range Rover Vogue ‘17 TDV6
