Peugeot 2008 e-HDi Allure (2014)

Hi, my car doesn't have sat nav options or screen mirror options so I'm guessing it's an old unit. I'm a bit puzzled as to why others have it in this model of car? I'm hoping a simple update will spring this fellow into life, as it's stands the touch screen head unit is a massive waste of space and technology in the car with only decent feature being dab radio which in all honesty isn't needed in a touch screen unit.

Anyone any advice on updating, upgrading, costs etc.

Thanks in advance
David
