iPhone 5 w/6.1 now unable to connect to Chevy vehicle

iPhone 5 with 6.1 is unable to connect to 2012 Chevy Silverado. 

using lighting to USB cableshows USB device then shows no USB devicecharges just finebluetooth for phone calls works fineit was worked with since August 2012 from iOS 6 up through 6.1 beta 1-4

Going to try remove the bluetooth profile and pair again to see if that has any impact but expect it shouldn't.

Anyone else have issues?
