Just to continue with the NSX owner's favourite pastime of spotting minute design changes from year to year, here is a pic of the lenses on my 1992.
Regarding sat-navs and routing, it is possible to plot a course on Google maps, download a gpx file which can be imported into some sat navs. You can then specify the exact route you want, and using Google is quicker than creating a route on a satnav.
There is even free software available just for this purpose that uses the Google map engine, and then creates a file for your sat nav.
I have created the route of choice to Le Mans, rather than take what the satnav gives me. I can then avoid the town, the crowds and get in to the campsite from the rear.
