We were just up at Marquette, and did ok with our Garmin Nuvi 260.
I think it was a combo of the Garmin + instructions from the school website.
Ran into the same issues on I-294 just west of Chicago, (also I-355 new
south extension),
with the ongoing tollway construction and ramps closed, gone, moved, etc.
I belive that TomTom has a user feedback & update capability
to handle those ongoing types of situations - ramps closed, detours, etc.
