Well...I don't have a ton of time to read the entire forum since I'm at work, but I saw some issues with TOM TOM causing the speed issues. I'm going to stick my neck out here and suggest trying Mapopolis on it. I know, I know...no 3d view and it's only pt. a to pt. b and no stops between, but i used to use it when all I had for GPS was a RadioShack reciever and a PocketPC. Worked great for me, perfect voice pt2pt nav, fairly accurate addresses, fast on-the-fly route re-calc for when u miss a road...I mean there's construction ! I'm going to try it out this week when I get time. CDR...I see you're going to try this out? I'm using MC2.0 let us know if you find a good way of embedding this in!
Ok, out b4 the boss checks my cube...damn I hate being a cube monkey!
