Chasing newer and newer versions is pointless, did that with standard 510, 3 different versions made bugger all difference, now have 686c dab, so no ssd but still no difference to my oem b version I started with, yes the screen is led back lit, do you notice, not one bit, just get cheapest dab you can as in 3 months they'll be another 100 new versions as vw pump them out left right and center changing the letter on the end for little pointless reasons
