I have a Nexus 7 installed in my 2008 Subaru Legacy (Liberty here in Aus).

I am trying to install a RCJoyCon Exr so i can control the Nexus with my steering wheel buttons.

When connected, the JoyCon Explorer software is able to detect all the button except for the down arrow.
I also noticed that when the joycon is connected, some of the buttons no longer work. For example the volume down and mute buttons do nothing and volume up does volume down.

Has anyone installed one of these in a Legacy (or Liberty), or has anyone had any problems like i have and managed to solve them?
