There seems to be something wrong in Google's vCard exporter. In vCard version 3.0 the colon character must not be escaped anymore¹. I changed the URL line to item2.URL:https://www.bmwsouthpoint.com/ and it works as expected.

The original vCard passes validation checks and is not wrong per se but the escaped colon \: is superfluous and thus interpreted literally as part of the URL.

I see. Would that just be when it appears in a URL?

If so, I'll try sed'ing my DB to get rid of those and see what happens.
