It is almost like going from a horse and buggy to a new caddy. This thing is really fast with routing, the XM works fantastic, the map detail and screen size are real good. I can do a long route about 100 times faster then with the SP3. Jon, all I can say is Thanks for all your help and information. I am going to wait until Spring before I turn on the weather. Holly and I went through a few real bad thunder storms last summer. Maybe this summer we will be able to skirt around most of them. I also want to say Thanks to DT for his help.
