Main screenin
Main screen size measures the central display diagonal. It matters because software controls navigation, charging preparation, assistance status, updates and basic cabin tasks. Bad software can make good hardware feel unfinished.
How to compare it
Bigger helps maps and split views, but interface design matters more than inches. Check glare, physical controls and whether key actions stay visible.
- Judge the feature in normal driving, not showroom mode.
- Check whether it depends on subscriptions or market support.
- Prefer clear controls for tasks you use every day.
What changes it
Software usefulness changes with update quality, menu structure, phone integration, subscription rules, regional support and how well it talks to the battery system.
- Native navigation can trigger battery preconditioning.
- Phone projection may not control vehicle energy features.
- Subscriptions can change what works after purchase.
Common trap
A large screen can make the cabin look advanced while removing useful buttons for demisting, mirrors or climate.
- Feature names vary wildly by brand.
- Subscriptions can change what remains useful after purchase.
