The first paragraph lists the added display features

When I use the durametric, it tells me the OBC is enabled, but I don't see the outside temperature on the display. It may only appear after installing the 4 stalk switch or the poor man's hack. I haven't done either.

Depends upon the car's year; the very early ones got the temp display by just activation, but after 2001 you had to have the stalk (or a substitute) installed before anything appears.......
