I have an AVIC-8000NEX that I've been trying to get to work with my Galaxy S5 in AppRadio Mode, but I have thusfar been unsuccessful. Though the S5 isn't on Pioneer's list, others have reported that it works, so I must be missing something.
I have the Samsung MHL adapter connected to USB1 and the HDMI connector on the 8000NEX. I am able to go into AppRadio mode, but all that I get is a mirror of the phone's screen (a small sun-like globe on a gray background and the buttons on the left side). The 8000's button's work (for example, I can access the phone's menu from the 8000's screen), but I don't have any apps available. There are two apps checked within the AppRadio app as compatible - CarMediaPlay and Waze. The Bluetooth connection looks good.
So, basically, it looks like it's connected, the screen is mirrored, but I can't access any apps. Any idea what I'm doing wrong? I'm happy to clarify anything that I haven't explained properly.
