I have a VDO GPS speedometer in my 1960 Land Rover. How well it works 
depends on how much of the sky the sender can see. And yes, a road lined 
by tall trees with narrows the sensor's view of the sky keeps it from 
working unless there is a satellite in the open space. I didn't want to 
drill a hole in my roof or compromise door/windscreen seals so mounted 
mine on the windscreen in front of the rear view mirror. So a satellite 
needs to be in front of me for the GPS to work. How well a GPS speedo 
works is determined by how much sky it can see. My mounting it inside on 
the windscreen I severely limited what my sensor can see.

On the other hand, the GPS has allowed me to determine speed by watching 
the tach, so when my GPS cannot see a sat, I look at the tach to 
determine my speed.
