Drive 52 - Maximum Number of Way Points

When I go on trips I usually design my route in Base Camp.  I mark way pints for the places I want to stop at and then design the route using them.

A while back I read that there is a maximum number of way points allowed for a Drive 52 route.  If so, can some one tell me what that is?

Also, am I correct that there is no limit to the number of shaping points (won't alert) that can be used?

Thanks,
