Finally got the WCPAA Wireless CarPlay / A-Auto - USB Adapter installed and working. I'm on Android and the Mrs. is on Apple so I had reservations going in.
I had a little problem at first trying to plug in the WCPAA into the end of my extension in the cigarette lighter mod I made and the WCPAA module would connect and disconnect. Thought it might have been a USB distance issue so I plugged the WCPAA module in where I plugged in the USB extension and then plugged the extension into the module and that worked perfectly.
I still plug in my Samsung Android phone in via USB connector into the extension in the cigarette lighter mod and tested the wife's iPhone 8 in there too and works flawlessly. Unplug one and plug in the other and everything sets fine and connects.
Then I took the new WCPAA one step further and set it up for wireless CarPlay for the Mrs' iPhone and it works beautifully. As soon as she gets in the car, phone in pocket the Avant-4 switched over to CarPlay and her home screen is active. I wish Google would get their **** together and finally release Wireless Android Auto but for now I am happy with the results. Video below.
