Darkoz, what year is your E46?
Mines connected properly. If it's not connected, I get 0 reception. I would say the overall reception isn't bad when you're in an area with a strong signal. I notice the signal to dwindle away a lot when I am on the highways and passing along mountain sides where my stock one would stay strong.
