I always get a " system not responding" message and its a distraction to constantly tap it to switch it off.
Thanks in advance for any guidance.
I have similar experiences to you, but haven't tried all the options you have. This system is the most infuriating aspect of the car. Radio, CD, phone/BT all seem broadly OK. Can't get an analogue clock display unless you first change the "skin". Can't test Mirrorlink because my cheapo phone doesn't support it, but 3rd party reports are not encouraging. Wi-Fi is OK, provided you set your phone up as a wi-fi hot-spot and connect the car to that, rather than trying to connect the car to an external wi-fi source. Also I have successfully streamed Spotify from phone to the car system via Bluetooth.
Although of course none of it works when the system crashes and reboots itself.
Regarding the "System not responding" message, have a look at this thread:
http://clubjazz.org/forum/index.php?topic=7624.0This is a fault, many - but not all - people get it. Latest info is that there is now a software update, but it might - if that doesn't work - require a hardware change.
