It's lacking some (needed) features
Tried it over the weekend with a 3 hour trip to/from DC. It correctly routed me around the propane-restricted tunnels in Baltimore ( I had already set my options to avoid 'propane restricted' streets). It wanted to take local streets around tunnels - I elected to drive I-695 around Baltimore instead.
Big problem - CoPilot has not implemented 'weight limitations' yet - It's on their to-do list. No idea as to timing.
Very simple voice prompts. e.g., 'take exit' without saying right or left or right two lanes, etc.
Rarely showed number of lanes which would work for an interstate exit.
It did show me the speed limits, and could sound warnings if I configured it to. This could be handy on local roads IF it those roads and speed limits are available. I'm not sure all speed limits are available.
Did not play with PIOIs.
Did not sign up for traffic alerts (My DW/Navigator checks with Sigalert.)
I couldn't play with it much; I was doing all the driving.
Google Maps is much more polished - visually, user-friendly, voice-prompts, saving favorites, etc.
CoPilot will be an optional GPS for me; Google Maps is my first choice, staying as cheap as possible.
