Ask HN: Is there a "good" (non-privacy horror) aftermarket HUD for your car?

I was surprised to see these kind of things on Amazon at $50-$100.

I have an older car (2018 Mini Countryman), and the lack of Android Auto is problematic. When I rent a car I realize how much easier life is with a fully integrated experience, especially for maps.

Are there any HUDs that people have found success with, which also respect privacy and aren't a support nightmare. I'm worried I will buy one and find out the integration is terrible, or that it is sending my data back to a Myanmar based call center.

Has anyone tried to build one using an android tablet?

I understand the concern, I have an Aliexpress HUD in my Forester. My question: why not just get one with no internet? If privacy is a concern, get one from an American distributor that supports CarPlay; My understanding is that internet is not shared with the HUD.

Doh, of course, that would make sense that it wouldn't need it's own Internet, just fed from your phone.

May I ask what model of HUD you are using? I did a quick search on AliExpress and there are a bunch.

Sorry, I don’t remember. They’re all the same on Ali insofar as they’re a cheap iPad clone with physical hookups. I paid around $170 because it’s a beater car. If I cared, I’d buy online in the US for $400
