Just returned from a trip using my 350 for the first time. No problems with it really just getting use to how it works. I've used a 2610 for several years. When I first opened a route in Trip Planner it gave me a list of locations along the route to pick from. If I picked the final destination it would calculate the route based on my preferences but not including the modifications made while planning like inserting points, etc. If I picked the location I would arrive at earlier it would calculate correctly. The route shown in the Map View was correct. Still can't figure out how to drag the screen to different positions on the map and navigation pages. It seems slow to respond, wants to drop pins where I touch and change screens. I'm sure it's just that I don't know the right method but I can't find it documented anywhere.
