HSP all the time into a DJ580, magmount antenna on the roof.
Yes, the laptop is reliable, but slow.

I'll be testing again in my truck later this week on the same routes.

I still think it is the combination of slow laptop/map redraw/low zoom 
level since a longer trip at higher zoom had no faults. My thoughts are 
that the map needs redrawn, so a redraw is started. By the time the map 
redraw is finished, I'm off the edge again. Due to screen aspect ratio 
this happens more on north/south routes. This really only happens at 
higher speeds, when I'm on streets at less than about 50mph, it doesn't 
seem to happen.
