Got notification of a pending update today. Currently 6.2 (2.4.239) since 6/5/2015.
There are things that need fixing. Navigation more often than not fails to draw blue lines on map for current route. Took friends (also Tesla admirers) to lunch yesterday and set destination for a UPS store. Codec got stuck in infinite loop trying to announce routing instructions. One big long Max Headroom hiccup. Got to use the example to point out to my friends how the turn signal click was synthesized through the sound system because there was no turn signal audio feedback when the stuttering navigation voice was stuck. Meanwhile I was trying button combinations to find the right pair to reset the center console, which finally cleared the codec infinite loop.
