I’m not sure a lot of you are reading that they are replacing ACP and AA with built in Google apps, including Google maps for navigation; they aren’t eliminating the functionality, they are replacing it.
I think I would prefer this over slaving my phone to the car because there are some real annoying things about AA when I try to use it while connected to my car. The only big question is: do they require separate Internet connection or can I use my unlimited data plan phone as a hotspot. Having to pay for more connection services would piss me off, however I read somewhere a few weeks back that connecting to the Internet via a hotspot was supported.
