No, sadly not.
Pros of nav high:
3D maps in citys
Full map on VC AND main screen. (But I suspect thats a software restriction not a hardware issue as mine has cocked up and let me have it on both screens at once on a couple of occasions with no lag or issues. Sadly soon as I program a destination it goes back to normal again.
cons:
Can’t update the maps for free like you can with the non high version. For me that’s a deal breaker.
