I live in the US and bought a 2018 EX-L. That said, I can't seem to find a way to add any apps to my system. I can see an "Add" Icon and a "download" icon, but whenever I put anything in the flash drive port with APK file extension, the install button is grayed out. Even though I have put the car of Wifi, no options appear for downloads. I don't see much help on youtube or on the web and the dealer is of no help. Are US cars locked out? If so, wonder when and why? Thank you!
