Is there a way to update the DVD with the most recent POI and roads? The unit doesn't know 1/3 of the restaurants / gas stations around here and when I was in Philadelphia it was off pretty bad as well... is there a way to patch it with the newest updates? (it's a 2008 tC SNS)

 

Oh come on, I'm sure someone's attempted to do this before.

 

as far as i know because it is a dvd loaded navigation system there is no update until you have a new dvd. for the price you paid for it i would imagine when the dvd's come out you will be notified

 

yup most major nav updates are yearly if then
