Hi 

 I recently purchased an Iphone4s hoping to take advantage of this HU but I'm having issues getting any apps to display excluding Netflix which works without issue. 

 I was under the impression that youtube, nav free etc would work the same way but I get nothing except a black screen. I'm hoping I'm missing the obvious and any help is appreciated. 

 Both my HU and phone have been updated. 

 Thanks!

Avh 2400 dont support appmode

Odd as the website claims it does. http://www.pineerelectronics.com/PUSA/Car/DVD-Receivers/AVH-P2400BT

Maybe it just has very limited capabilities? (Though I'd assume Netflix & youtube would be similar)
