With the popularity of Android Auto/Apple Car Play growing the power-only USB ports are slowly dying away. I`ve found the "charge only" USB ports of little use anyway since most don`t even provide enough power to keep a modern cell phone charged AND allow it to be used for things like bluetooth streaming of navigation. I end up using a charger in the 12v lighter port anyway.
