I took my car for service at the dealer yesterday (Saturday, July 6th) and asked them to update the firmware. That's what's needed before the upgrade, right? How can I be sure that the firmware I have is what's needed before the ACP upgrade?OP: Install the software yourself and get it done at that shop. I have no idea what he is talking about with the antenna?!?! I don't think that's a thing. Watch the install video. There's no mention of this. They are just USB ports.
Thanks.
