Yes, it still works. I have not experienced a single glitch as far as the hdmi connection is concerned. I have a few minor complaints, but this is more limitations of the concept itself (all it does is mirror your phone screen on the factory screen, provide touch screen feedback and play music on the factory sound system). This might seem a bit negative, but the positives should be obvious. All in all I am very happy with the system:
-The initial warning screen that pops up when you start the car is even more annoying than the warning screen that comes with the lexus sat-nav (where you have to press 'I agree'). It does not seem to be any way to remove it other than waiting for what seems like ages (probably only 5 sec or so). I'm pretty sure I've read somewhere that this screen can be removed, but I have only browsed through the instructions quickly. The most annoying thing is when you start the car and immediately engage reverse. The reversing camera pops up, but after a couple of seconds this warning screen takes over. In that case I don't know how to get back to the rear view camera without changing from reverse to park to reverse again.
-You still have to use the factory hands free for phone calls. This means that during phone calls the factory phone screen takes over. You can press 'Audio' to go back to the phone mirror screen, but during calls, the touch screen does not work properly. I have not really looked into this carefully. The touch screen feedback is done via bluetooth, so maybe there are some bandwidth problems? Could also be phone dependant. If you do not connect to the factory hands free, the call will be on the phone (sound and mic). I find this strange, since all the other apps will play sound through hdmi on the cars audio system. This is a feature of the phone, not the iVic. You get the same problem if you connect the phone to a TV and try to call or use Skype.
-When the parking sensors activate, the park assist screen will take over (as it should). But by default it will return to the factory sat-nav screen, not the phone screen. So you have to press 'Audio' to get back to the phone screen. Maybe there is a way to set 'Audio' as the default screen?
-It can sometimes be difficult to navigate within apps as the screen does not support gestures like swipes and pinches (zoom). Swipes kind of works, but not properly like on your phone. Simple tasks like unlocking your screen or zooming into maps could be difficult. I wish google maps had zoom in/out buttons. The answer might be to mount your phone somewhere accessible so you can use it as a sort of macbook style track pad. At the moment I just keep in in the storage compartment under the armrest or in the cup holders. It is probably also a good idea to mount the phone for navigation purposes to set the compass directions.
