This app is a big problematic headache. It can be enables by physically plugging it in with aUSB cable. Normally this would not be a problem, however it's super glitchy. Loses connection constantly even if you BARELY touch the cable. Countless x's I've had to pull over, kill the engine, unplug/plug back into USB several x's, restart my phone, with inconsistent results. Today's issue: No Display. AA is no longer appearing on my vehicles display, i.e. siruis xm, google maps.
