This is not equivalent. The key distinction in the device from OP's post is that it actually connects to the OBD port in your car, giving you a direct connection the cars systems. The one you linked does not seem to do that at all.
I have Android Auto and love it for navigation/music, but it is missing any car specific controls, eg. climate controls, reporting speed, maintenance, etc. I have to exit out of Android Auto and into Sync to access some specific functionality only available through the Sync touchscreen.
Is this just a case of the manufacturer needing to provide the right app, or is that information not available to third party apps running in those environments?
I just want the best of both worlds .. trying to hold onto being the main user interface feels short sighted. I'm not going to NOT buy your vehicle because I can use Android Auto vs your custom UI, so having both available shouldn't be a negative to the manufacturer.
There's a lot to be said for air gapping critical systems.
Some cars are built this way too, thankfully.
