i am going to be buying hardware and software for copilot based navigation systems for several trucks for the company i work for.

i want to know if i should get the copilot receivers or get the software and different recievers.

Last week when i was in D.C. i had trouble getting a fixed position at night while moving and even when stopped under trees. it ussually does not have a problem, but that one night it did.

what does everyone else think about the copilot receiver?
