Does anybody else is having connection error when playing music from Iphone 4 using USB cable and Bluetooth connection? It does not happen all the time with me, but it happens in the middle of playing music.

 

If you're using the USB to mainly charge, I would suggest using the power port instead. Having an iPhone plugged into USB kinda puts it into iPod mode (for lack of a better way to explain it) and messes with the bluetooth.

 

+1, I'm experiencing the same issues so I just use the bluetooth for audio and power supply for charging

 

Can I use the USB ports to transfer / view images from my iPhone onto the Nav display?

 

yes its a common issue with the 2014 IS...

it has to do with apple's AIRPLAY system....the system gets confused...so my recommendation would be to disconnect the audio player through the bluetooth when it is connected through USB

 

no you cannot directly, you would need to put the photo on a USB flash drive...
