You guys are getting worried. My Ford Taurus Sho's infotainment/navigation/phone integration is great. Actually the Navigation is the best I've seen. Combined with Sirius traffic/weather it's impressive.
The phone sounds crystal clear on my Tesla on both ends. Most people can't tell I'm in the car. Works great. Automatically connects to my phone without having to click anything. My brother's Ford Sync is a chore to connect a phone -- sometimes it works automatically, other times not...
Tesla's infotainment is the easiest to use and most responsive of any in car system I've used. Most in car systems are mazes of terrible UI design, and slow, low res screens.
The voice commands work well, but there aren't many of them. Navigate/Drive/Where is, Play/Listen to, and Call/Dial.
Navigate to is super useful, you can say an address or place name, and it just works. Navigate to 100 1st Street. Navigate to Whole Foods. Where is Whole foods. Drive to Whole Foods on Emerson. Navigate to Whole Foods in Palo Alto. My brother's ford has strict syntax requirements and if not done correctly, it just fails. Tesla's implementation is much more natural.
Same with call. My girlfriend has a non-traditional spelling of her first name, and a long German last name, but Tesla's system works perfectly. Cannot however, say Dial 867-5309.
Play or listen to for music commands. Can say: play Jimi Hendrix. Play All Along the Watchtower. Play All Along the Watchtower By Jimi Hendrix. Play Bob Dylan All Along the Watchtower. Natural, and just works. Cannot say Play FM 104.9 or play USB.
The google maps display in the Tesla is excellent. Huge, easy to see, and easy to manipulate. Traffic is displayed in real time from Google, which is super useful for making decisions. You can just look at the screen and see "oh the freeway is backed up for 10 miles, I'll take a different route". The nav, however, doesn't seem to take this info into account when navigating (it seems to use some other traffic data company).
What is there works great, mostly better than the competition. It's the stuff that isn't there that is slightly annoying. But mostly it just works. Not being able to voice dial a number has never been an problem for me. Changing music source is just a flick of the steering wheel control. So, not a big a deal that voice command cannot change between FM and AM and USB or Internet.
