Did anyone else have problems today with a bouncing GPS signal? Today was in the 90s, blue sky but hazy with a high ozone level. We have a Garmin Map76CS and it was all over the place today. I'm wondering if it could be atmosphere or if there is a physical problem with the unit. It would go from 2 satellites to 6 then back to 2-3 and recalculate over and over and over. I'm up to date on firmware upgrades and cannot see anything on this recalculate problem on the Garmin site. Lefty - if you are reading his, we have the same unit. You have problems today?
