My GPS went out and displayed the same symbol. Actually, my whole audio, Nav, Bluetooth and map screen was out. It's been to service 3 times since October for this, but the first symptom was the GPS going out. It was fixed twice but never lasted more than a few weeks. I kept noticing that it always seemed to go out after a heavy rain. I just had the car in Monday and Thursday for this and it turns out there was a good bit of water in the right rear quarter panel and the ACM was soaked. I was told there is a grommet that is notorious for leaking in the Explorers. The ACM and modem were replaced and the leak was supposedly sealed. I'm guessing the leak is at the antenna and water runs down the wire.
