Is the Apple adapter you purchased; the USB & Media port cable?
My wife has an iPhone 4S so I've fitted the Apple loom to the centre console,
Or have you gone all out mirror link where your iPhone is fully functional on screen?
As for the reverse camera,
Pioneer released a firmware update which solves some reverse camera glitches,
I presume you have it connected via the BC input (brown socket) not the yellow AV input,
The camera takes a minute to display when reversing,
I suggest fitting an auto relay to the trailer loom if possible,
I can work with you on this later tonight when i get time,
This will need no switch and automatically deactivate reverse camera when trailer is fitted,
My camera is a bit fizzy at times,
But i didn't earth to body i earthed to reverse loom so that is probably the issue.
Thanks for comments,
Its bright now so im going back out to install,
Talk to you later
Updated to latest firmwire and still the same.
I have my mobius connected to video in and back cam to brown like you said. My old sony headunit i could just tap rearcam icon and view th cam with music still playing. But this unit it doesnt seem to have that option? Maybe will have to use a "Y" splitter and use in video out port - can switch between front and rear that way? I also use the rear cam for parking too and to watch tailgaters lol.
Got the genuine apple hdmi to lightning adaptor which will try next week to mirror screen - allows internet browsing, location sending to friends n family etc, and more. Car play is limited but still great!
How you finding the headunit? Still learning mine haha.
