I'm looking into purchasing an AIO-5 to use apple carplay for maps and music. There is an easily accessible switched live that wouldn't require me to splice into any of the stock wiring on the bike. I was wondering if its possible to run the unit solely off this supply providing I'm only using it for apple carplay? If this is possible how it is achieved? Will I have to connect both the red permanent 12V and the yellow switched cabling to this switched supply in order for the unit to function? Thanks
