ARGH, Android, I have a "apple", ie., I Phone 11. Not know ne thing on Android. But the Radio System is Android Capable, not remember wat they call it. Do a screen shot of your screen display on yer 8.4, so I have a clue what U have. There are a lot More PPL way smarter than I on this and maybe they can chime in. Not sure if your screen will display a GPS (like a Garmin), there is no input, but PPL have modified stuff. I use Maps off of my Phone and/or Google Maps, which will display on U connect screen when U hook up with a cable into the radio system. Actually running through your phone but displayed.
ADDED: Can somebody chime in here and help this OP, who R better than me and know ANDROID systems, since I have I Phone.
CAVEAT: I have an old Garmin that I carry when I take a trip for emergencies, used to Ride HD, but went to Honda for wife.
