From bcfa8087eafcf4d96fc70eaa10afdce4dcfd3655 Mon Sep 17 00:00:00 2001 From: Scott Murray Date: Wed, 11 Dec 2019 22:22:01 +0000 Subject: Initial steering wheel event support Add initial basic support for next/previous events from signal composer, mapping them to seek forward/back. More work will be required to handle the issues around both mediaplayer and radio both being running and differentiating which should handle the events. Additionally, complete transition to binding version 3 to clean things up.
