Tiffin Co-Pilot Navigation PC System

I can't speak to your question specifically, however after owning expensive built-in GPS systems and also owning several-hundred dollar Garmin units with lifetime traffic and map updates, I've developed a strong preference for the Garmin units. Why? Because GPS devices are still in a high-rate-of-technological-evolution. New features are being incorporated every year, map databases are more and more detailed, traffic reporting and avoidance, and soon you'll be seeing GPS units integrated with WiFi to display real time weather radar over your route of interest. Another button will give you the locations of the next 5 truck-stops close to your route-of-travel, etc. The built-in units can't keep up with all these new innovations. But, for a few hundred dollars, I can buy the newest features and stick them on my dash. Having had both, my dollars are voting for the portable units.

How about others.... anyone help with the OP post on Tiffin?
