Nuvi 2460 and Route Optimization - Only 2460 please

Hello,
If you have a 2460....

Do you use the Trip Planner?

Do you use Mapquest?

I need to route about 100 stops, and then optimize that route.

Can't do it in mapquest because

A). It only accepts 26 points
B). My 2460 won't read Mapquest gpx files

So how do you optimize routes?
