we got an ad in the mail to upgrade our tsx's nav software. it is almost 200 dollars for the disk. since we just bought a new TL, i took the new disk out and sure enough it work in the tsx also.

is there any big advantage of updating the software? can i get it cheaper else where?

 

The Acura Navi website lists what's updated on the new DVD. Most of the time it's just new roads added but sometimes there are other changes. If you don't live or travel to the states listed then you can skip it. I'd love to know if there's somewhere they can be gotten cheaper. I'll be backing up my DVD this week when I get a chance.
