Navigation routing upgrades???

Navigation routing upgrades???
Hi, I'm wondering if an updated navigation DVD updates the routing software as well as the database.
The reason I ask is that I just bought an 05 TL with the original navi DVD and the routing isn't up to the same standard as the $100 Garman unit I was using before.
I am on a trip from Toronto Canada to Hanover Pensylvania and the TL's navi keeps giving me round about routing that adds an hour to the trip (Garman = 7 hours, TL navi = 8 hours).
I've tried every combination of easy route, direct route, maximize / minimise expressways, etc. and The TL navi just doesn't cut it.
Does anyone know if the routing is built into the system or should it improve with a new DVD?

Wish I could just hook up my Garmin to that screen.

Apparently there are some options here. I found some people using torrents and burning a double layer DVD. Otherwise it can be ordered, apparently. Please see below.

I am torn with this one, the updated DVD obviously had new(er) roads on it so that helped with the routing but I cannot say with confidence that its any "smarter" with the routes it chooses.

Do not trust the hours the navi gives you, its based on a very low speed, like 50. check how miles to go there are on the navi route and compare that to the garmin one.

In fact it was amusing to watch how long the acura navi would keep telling me to make a u-turn back to its longer route until it would finally lock on to the garmin route. Only to diverge onto a longer route further up the road.
I think that the way these things work is that the database of streets contains hints about routing that the routing algorithm will use to work out its route. In this case a new dvd would help somewhat, but if the routing algorithm itself is built in it couldn't change. Thats why I was wondering if the algorithm was software that came on the dvd and could have been updated in the past few years.
I suspect that if you are just going on interstates it would be fine, but the trip I took was through the mountains heading south from buffalo and the navi just didn't like that. (and yes, I did try all of the direct/easy/min max freeway/ etc. options)
Is there anyone out there with a garmin or tomtom plus the new navi dvd who is going on a long trip and who is interested in doing a comparison test for all of us?

I think we could test the routing efficiency simply by supplying a start & stop location and then comparing the distances. Since a known errant route has already been documented, we just need to have someone with an 08 navi input those points and report the results.
I sure hope the software has been upgraded because I'm not too happy with my 06 version.
