I have a 2014 is 250 without navi.
I tested the mirrorlink funktion with galaxy sIII. The mirrorlink funktion in menu is greyed out until I activate the mirrorlink application in galaxy sIII. After plug into USB the menu is active, but the funtionality is very simple. I can only use the google maps but no other navi application. If I am using mirrorlink I can not swich on the radio or my ipod.
Now I am trying to test NOKIA, but I can not buy "NOKIA CAR MODE APPLICATION WITH MIRRORLINK" in the Nokia app store because my nokia 700 has an upgrade!!!??? Nokia support can not help and I could not find any solution in the different forums.
Xperia z, ZL, and ZR are compatibel with Mirrorlink in theorie but I would like to know how does it work in praxis. Alexch, in wich car have you tested the xperia Z?
