Preroll: No need to actually uninstall AppRadio app, just quit it. You CAN delete it, but I like using it from time to time. Do the steps I mentioned before, and below... and you will see on the x50 you dont have to have AR App loaded at all. This will NOT fix the INRIX issue of a black screen or make the new INRIX version work, this alternate method for loading apps is just a good way of isolating issues, and keeping problems to a minimum and I am kind of shocked no one has noticed this is how the x50's work.
VBLUE42: yes, I have full functionality, screen touch etc. Again, the AR App is nothing more than a nifty glorified launcher, it doesnt add or take away any functionality to the 3rd party app you want to launch. This is also how I launch third party apps that are NOT approved by Pioneers busted approval system. Apps from other countries and developers can all be launched independently from this method vs the limited catalog that the AR App tries to force down our throats.
Example of steps taken without AR App:
I load DashCommander (or any other AR enabled app such as Waze, Aha, Pandora, Mixtrax etc) on my phone, with AR App completely closed (or deleted) the phone when plugged into the lightning connector to the x50 will then change screens to DashCommanders (or whatever app you launched)"video out/AR mode" it may even say Pioneer AppRadio.. each app is different in branding.
On the head unit I then tap the AR button to switch the head unit into its HDMI source (thats all the AR button does in reality). It will ask you if you want to launch the AR App and to check your phone for prompts. Your phone will have an "allow and ignore" prompt sitting on top of the App you launched just tap IGNORE and you will soon see your app on the x50 without having to launch AR App at all.
On a side note: I believe iOS7 has actually IMPROVED its bluetooth stack. I am noticing apps such as DashCommander that communicate with my Bluetooth OBDII plug are far more stable these days compared to iOS6. Dash commander used to lose connection with my OBDII plug all of the time, forcing me to do a reconnect. It was a huge hassle that made me want to throw the x50's out the window. Looks like it was Apples bluetooth stack this time around!
