That could be. Sometimes when you think the car is the issue, it turns out to be the accessory, and vice versa. I'm using a
wireless CarPlay adapter in my car and it works pretty well, but it's often slow or needs unplugging and replugging in order to work. I assumed that all of this less-than-optimal behavior was the fault of the
CarPlay adapter, but I just took my car in to have several recalls addressed and was given an Elantra loaner in which my
wireless CarPlay adapter is much better behaved. So at least some of the issues I was attributing to the adapter seem in fact to be born of my car's lack of finesse in dealing with the adapter.
