My Garmin 750 has been looking for satellites since Sunday evening. I live in McMinnville & took my son to PDX Sunday evening & the GPS was going whacky. At one point it said our elevation was -1150 ft and it couldn't find any satellites today. I'm thinking it's because of the forest fires but was wondering if anyone else is having the same issue. I updated the s/w a couple of months ago so that shouldn't be the problem.
