Hey there..........is there a link or website to learn about the navigation systems for different years? I have seen posts about getting XM with nav and weather. which systems do this?

 

There is a difference between the '04-'06 and '07-'08 Navis-- the later Navis had access to an additional-subscription cost instant traffic service based on road sensors (in addition to the regular XM traffic channel broadcasts) as well as a rear-view camera viewed through the Navi.

I think there's a thread on the model year differences in the 3G Service Dept/Garage that is stickied on the main 3G TL page.

Anyone can view the Navigation manuals for any year, as well as the owner's manuals, through the Acura owner site (even without registering); see: http://owners.acura.com/vehicles/warranty .
