I'm finding my success rate to get Summon working, in a reasonable amount of time, to be about 50%. Often times it hangs in "connecting" mode for quite a while and then asks to reconnect. Other times it says the vehicle proximity sensor is covered, wherever that is. I've tried opening the trunk or operating the door handle, which means the car is certainly recognizing the proximity of my iPhone, but that seems to confuse the system even more. The times that I'm guaranteed to not connect is when the request follows me saying to a friend "Hey, check this out..." Then I fumble with the phone for so long that it ends with "Nevermind, get in." Anyone found a quick and easy way to ensure a connection to use Summon more reliably?
