The CoPilot does not even have any specs listed, so I don't know if it even has a good chipset!
And it sounds like it does not have a standard nema output, Garmin did that as well on some of their units and thats not nice that you are limited on the software you can use
I use this unit, its smaller and sealed better than the BU-353
Sold about 30 of them ,and no failures
About $20 more,and it uses the same chipset so perfomance would be equal to the BU-353
