Hmmm, the "open cradle" experiment doesn't seem to match my results. Mine approach was kinda less sophisticated than the sfax standard. I had the phone in my hand and it had two bars, I put it in the cradle and closed the armrest and it reported 4 bars. Driving through a former 0-2 bar location, I consistently get 3-5 bars in the cradle. iDrive lying to me? Could be. Well, except that I've held calls through that dead area where they would previously drop. That suggests the reported value might be accurate.
I'll see if I can do a more specific test. How do you read the phone in test mode with the armrest closed?
(Eager to see the remote video monitoring system sfax whips up to surmount this challenge.)
