Tried this version of Igo Israel on Sony xperia Z3c too. Same issue. With any language and tts voices engine installed. So I think is the program itself or the android lollipop. Tried nextgen, exits at program startup,i think is license issue, using tomtom 2015.03 maps. I will try today with here q1 maps. This is another thread already, so thanks for you help. Sorry for the rough language but nobody answered to a bloody question !!! :D
