Small sample size, but I am returning the Vigo Series port you mentioned. When connected to a OEM apple firewire USB cable, the screen is extremely garbled and unusable. I disconnected it and went straight from the female usb Alpine cable to the apple firewire, and problem solved.
At least one other person in the Amazon reviews saw the same thing. Too bad as I liked the look of the Vigo. I'll need to add a dremelled port or find another Vigo style port that has a better USB connection.
This is a brand new Alpine ilx-w650
Only when connected to CarPlay over the Vigo port does the screen look like this. On Radio mode or with the Vigo port bypassed, no issues at all.

Looks to be the same as

For those wondering. Both come in the same box covered in Japanese script.
My FM reception is OK using the large standard antenna port, but without the smaller one I have zero AM reception. That kinda sucks, but the whole reason I upgraded was that I listen to podcasts 99% of the time that I want talk radio.
