*update*
I am using my jailbroken iphone 4 with my avic flawlessly
I want to mirror my phone to the navigation
and it works perfectly
only one problem I've got here is iphone 4 is too laggy
so I decided to use my iphone 5s and bought cd-iv202navi.
unfortunately, I haven't found any way to work with it.
However, today, I exprienced some strange behavior of my avic
even though all the hassels i went through here http://avic411.com/index.php?/topic/81643-2015-avic-z120-map-update/?p=342370
except the initial try of getting it working, I haven't connected iv202navi to the gps.
I just checked if "ipod settings" would show up in the av setting menu.
I am using my avic with firmware 5.0 now
i connected iv202navi today and checked if it would work with a iphone5s
when I connected my iphone5s to the gps
"ipod" in the av source menu did not show up (which would show up on the left side of screen when you connect ipod to the avic)
then I update firmware to 5.1
still everything looking promising until the "program foreced write" step
after this incompleted update, still no ipod setting option in the av setting menu
BUT, in the av source menu (which is left side of screen), there was ipod menu.
I didn't even connect my phone to my avic
so I connected my jailbroken iphone5s to the unit
and my iphone5s screen mirrored into the avic, also was getting charged.
then I tried my iphone7+, it mirrored into the unit, also getting charged.
but no sound.
I decided to reset the unit by disconnecting the battery. (I solved some iphone connectivity problem before with this method)
after the reset, ipod menu on the av source was gone.
I rolled back firmware to ver. 5.0 and updated to ver 5.1 a couple of times
but haven't come back.
I felt like i almost got it...
and I wonder if there is any possible way to keep the ipod menu in the av source even though iphone(ipod) is not connected to the unit?
