Is there a website where I can order an upgrade, I still have the original. Does the upgrade work with teh software as well or just the mapping?

 

go to the acura owner link website you can order a new disc for $185 plus shipping, i think that's the price it's 180 something for sure.

That's the website that most of the people here used when ordering the new disc (including me). I have a 00 TL also, and the new disc works perfectly (I upgraded from the original 00 disc also). I'm not sure what you mean by software and mapping, but the new disc has the same interface (screens, buttons, controls) as the old disc, it just has more information (more POI's, streets, etc), however it lacks Canada. For me, due to the developing area I live in, the upgrade was worth it. If you’re in an area that hasn’t changed much since your current disc was released, you may not benefit as much (unless you want a new listing of POI’s and the new “voice”).
