Decent

Far better cosmetically than the stock app on the AVH-P8400BH but the functionality leaves some to be desired.
The audio output lacks in comparison to the stock app possibly because sound retriever is not enabled for it.
My second irritation is that the app / advanced app mode is buggy. Switching back and forth between apps, say car media player and navigation (Navfree) usually causes the touch to cease or the display to go blank! You have to unplug, restart the app or even sometimes the iPhone to restore functionality. Trust this is more than a minor irritation on the highway and potentially dangerous for anyone.

Pioneer needs to throw their weight behind their products or lose customers.
