Sorry there Lugnut , but I've used the software, as have quite a few members here. I doubt you're gonna find many drivers taking the positive spin as you have. [Actually, your post sounds like sumthin out of a product brochure] And no,
training is not the problem. The software is just lousy. The maps data is horrible and will at best,only route you properly 70% -85%of the time. Countless times the directions tried to steer me in ridiculous paths. Not quite certain where you got your market share numbers, but can assure you it's not based on Copilot sales. Possibly you're confusing Copilot with the actual working application, called PC*MILER.
Huge difference between the 2. One works well,Copilot.....not so good.
