Am I the only one who wants less integration with normal phone functions while driving, not more? I use my Android phone with a mount and Google Maps for navigation, but it's a pretty horrible and distracting experience. Even though you're actively in driving mode you'll get all sorts of notifications / message popups you'd normally want, but I don't want them while driving. There needs to be some OS-level quieting of everything except the navigation and phone calls, you can't put the phone in airplane mode because you'd like real-time traffic updates. The least crappy way I've found of dealing with this is using an old android phone without a SIM card and nothing on it except Google Maps, then teather it to the main phone (with SIM) for network, put the main phone on silent and throw it in the glove compartment. But that also sucks since I'd still like music, podcasts & audio books. So now I need to sync those too to that phone, and it leaves out using the phone (as in, talking to people via voice) through the car speakers.
