I'm a technology guy, I was just curious. I think the 480 tip is probably right, that screen is pretty basic. Not sure if I would use it, it's just a novelty.
I'm pretty impressed by the 'back end' capabilities of that unit. Plug in a couple USB drives and it computes voice tags so I can use voice commands for up to 100,000 songs. That's pretty impressive.
But the UI is pretty primitive, to your average smartphone user. I want to customize my home screen, with a background image, I don't want to see that same boring power on screen every day. It has internet access via OnStar, I want a weather forecast. The Sirius XM interface is very basic. The 'apps' should update like smartphone apps. I don't want to take it to a dealer. And it should run android apps...why not, android is essentially free so up the resolution and let people have their own apps and home screen.
I realize it has to be a highly secured system - it has control of your vehicle. But if architected properly entertainment apps could still be safely updated. Though we would see an entirely new class of hacks and recalls, as soon as the system was open to attack.
But smartphones set the bar, and as incredible as I find the systems in this vehicle compared to my previous 'dumb' 2007 Acadia, vehicles have some catchup to do. GM just announced 100 new vehicle system design jobs in this area in Oshawa, where I live. After doing 35 years are of IT architecture work, this would be a fun area to work in.
