QUESTION - Have you seen anything that was published before 9/13/2010 that discusses:

If so, please submit evidence of prior art as an answer to this question. We welcome multiple answers from the same individual.
EXTRA CREDIT - A reference to anything that meets all of the criteria to the question above AND ALSO displays multiple potential navigation routes simultaneously
TITLE: Navigation device with alternate route calculation
Summary: [Translated from Legalese into English] A navigation device that calculates multiple routes for a driver and displays them simultaneously (without the driver being required to request a different route)
- Publication Number: US20130173159 A1
- Application Number: US 13/822,791
- Assignee: TomTom
- Prior Art Date: Seeking prior Art predating 9/13/2010
- Open for Challenge at USPTO: Open through 12/31/2013
Claim 1 requires each and every step below:
A navigation device, the navigation device operable to calculate routes to one or more destinations,
the device further operable to provide a navigation instruction together with
an alternative navigation instruction.
In English this means:
A navigation device which calculates routes to destination (or multiple destinations), which:
provides navigation instructions; and
provides instructions on alternative routes
Good prior art would be evidence of a system that did each and every one of these steps prior to 9/13/2010
You're probably aware of ten pieces of art that meet this criteria already... separately, the applicant is claiming displaying multiple routes simultaneously without the driver requesting a "re-route"
"Providing multiple routes to a driver" from the Applicant
