However you can not get a sat lock if there is no data reception initially.

I had a real world experience w/ my mogul where this happened exactly. I drove to sequoia national park for a camping trip, using garmin. I was able to use it fine on the way there, even without having the slightest bit of cellular reception for many miles inside the park. However when it came time to leave the park and head home i wasn't able to get a sat lock until i was back in an area w/ cellular reception.

I think its different on my Pro.
