Please fix this app

I have told many about my purchase of my pioneer radio and what it can do but I can no longer get the gps or app radio to display on my head unit! It was great while it worked but now is only good as a Bluetooth phone or iPod connection! Please fix this problem! I have told my friends to hold off buying a radio like this until this is corrected so they r not paying for more than they get like I did now!

Cancan am about AppRadio, v2.9.1
