I had been using CarPlay quite often and just started using Waze via CarPlay when that became possible recently. As of a couple days ago, however, the USB port seems to have stopped recognizing my iphone or any other device. I've plugged in several devices using several different cables (including the ones that used to work just fine) but Mr. Clarity insists there is no device plugged in (the devices do charge when plugged into the USB port, but apparently no data transfer). I'm thinking the USB port (or something electronic in the car) is toast, but does anyone have any other ideas?
