I'm on Raceman's band wagon on the MS S&T program. I have not used the CoPilot program/system, but I've heard lots of comments about the speed of the updates, and lots of other "issues".
I'm running in a cargo van, and I use MS S&T on a laptop, and I love it. Works great everywhere I've been, and has been a great help in Canada.
**NOTE: Can CoPilot find a White Castles location for you, at 0200hrs when your craving 6 double cheese burgers and some onion chips? I think not!
