I just purchased the TT Car Kit and had two questions: 1. After initial pairing, my iPhone will not automatically pair with the Car Kit on subsequent usage. Nevertheless, GPS audio still comes out of the Car Kit speaker but phone calls do not. Is there a way to have it pair automatically (like most BT accessories do after initial pairing)? I can go in and pair it again manually but this defeats the purpose. 2. After my car ignition is turned off (and with the iPhone out of the Car Kit cradle), the USB charger light is still on. Is this normal behavior? If so, it seems that the battery drain is a risk.
