Hi,
I recently installed a Pioneer 4100NEX in my 2014 Jeep Patriot. Android Auto works great with my Samsung Galaxy S5 running Android 5.0, but I can't get App Radio to work. I purchased the Pioneer CD-AH200 kit, and connected to the HDMI and USB cables using the MHL adapter. The phone is also Bluetooth connected to the radio. I installed the Appradio app on my phone and started it. When I hit the Home key on the radio the App button has an X and no apps appear. What am I doing wrong?
