I quite like the look of the Becker unit. It's period accurate as I think modern car stereos have become ridiculous, looking like children's toys, spaceships etc. Not to mention they've become dangerous to adjust or even turn on! This was a pet peeve when you try to replace a car stereo in a 70's vintage vehicle, for example. Even though it late 90's onward, it still looks dated - which is good
There is a user who set up an iPad mini into his (now sold) 2001. That looked cool, is cheaper and offer greater flexibility - though it still can be dangerous to operate.
