You can control from the smartphone screen. S2А mirrors the smartphone screen and can be controlled both from the Multimedia car screen and from the smartphone screen.S2A still cannot work with non-touch screen device
do S2E work stand alone without S2A? meaning if I do not want to use S2A but I want other phone connect to my car device, can it still connect to Android Auto thru S2E?
and S2E still no English?
