tcassidy,
Yes, I found the issue. In Google Earth, the box to the right with places, I had a box checked named "Real Time GPS". I don't know if that came on when I updated GE or if it happened when I installed the software for my BU-353. I think there may have been a conflict between GE and Earth Bridge, while the "Real Time GPS" box was checked in GE. I'm not really sure.
I did a 15 mile round trip last night after getting everything going. I set it up so my track was recorded.The line that follows my track was very broken and always way left of my actually track. If I turn or drive down a road, it shows me about 30m to the left. I thought is was kind of amusing. Look Ma, I can drive on water!
I'm still playing with the settings and doing more searching on here and the net. Not much out there and Google search keeps bringing me back here.
