Proceed MJ 2020 – What added value Digital cockpit + 10,3” Navi?

Hello, I would have the opportunity to get a Proceed GT MJ 2019, day registration 04/2020, much cheaper (approx. 2000,- EUR) than the current model. Approx. 28,000,- EUR to 30,000 EUR The GT would have all packages and I see as the only difference the digital cockpit as well as the larger 10,3 inch Navi. Do these 2 features really offer this significant added value? Is the UVO app usable with the previous year’s model? … and are there any other differences to the current model? would be grateful for answering these questions as I will make my purchase decision dependent on it. Best regards and nice weekend Kiramisu
