pioneer 7400 and usb problem

[cmw5e 6]

i was driving home last night and plugged my phone into the usb and nothing happened , but i just drove home with the radio on and didnt pay much attention. i went out today to mess with it and the usb will say its charging my phone but usb and pandora wont show up on the cd player. i kept scrolling through the sources and now when i scroll through them the cd player just shuts off. any ideas how to fix this?

turn your phone off and back on?

its an iphone so i turned off all apps then started my music and pandora again and still didnt work, whats really puzzling me is when im scrolling through the sources it just completely shuts off

turn ur phone off completely and turn it back on..

when i plug my iphone in you cant use it from your phone unless you hit a button on the radio that lets you control it remotely.

idk about the cutting off deal, but my pioneer 3200 or whatever the model is when it starts actin up i just restart my phone and it works.

restarting my phone does nothing. it still shows its charging but only thing coming up on the source menu is tuner, cd player, and aux

the usb actually comes up now and says error 19 but still no pandora. i reset my phone and it still does the same. the phone will go to usb and says error 19 and if i scroll through the source more than 2 or 3 times it shuts down

it charges my phone through usb but still wont play music. the cord wouldnt play music through a buddys system either. it charges fine on my computer. my phone hasnt had any updates or anything but im going to go buy a new usb cord and hopefully this fixes the problem
