I don't know if this has been covered before but I can't find it on a search. The sat nav on my IS200 sportcross will not let me input any addresses, all the other functions work but when I try to click on the address button nothing happens. It also isn't highlighted as if the function is not available, I don't know if I am not following the correct procedure but then again I don't really see how I couldn't be. Any help or suggestions would be greatly appreciated.
