I'm sure it will be good. I've had a bit of a roller coaster ride on the subject given that I'd like to have the display assuming I go for the
Ateca Plus as I call it (the one that should have the Kodiaq' s legroom). Finding that Seat UK had dropped the Navigation Plus from the configurator of the
Ateca, but it's in the December 2017 price list so I think it can still be ordered.
I don't think I would put the map display up on the dash display console, the next turning does me on the MFD with the maps shown on the 8" screen but the flexibility of the digital display would be good. So I'd order it I reckon and play with it but I suspect if I couldn't keep the speed display, plus the next turn in the middle and map, I wouldn't bother with the map and get it to display what I currently see on my
Ateca .
Given they are all the same models between the VW, Skoda and Seat but just additional extra software which each add, but Seat doesnt add that much. I reckon the limitation will be the same on the standard Seat screen as VW, not the end of the world. I don't reckon Seat will be programming at that level. If I was in the market now I'd be looking at how it functions on VW and Skoda. If Skoda is the same then you can bet it's inherent.
The map updates split between the standard Mib2 and Mib2 High but the updates are common (the same irrespective of brand for the standard, ditto High). The display hangs off the unit. It's going to be the firmware that dictates whether the standard unit can multitask the map display. Given Seat and Skoda follow VW that's why I reckon it's going to function as in current VWs... but we will see.
Something to look out for when you get in the car and report back.
