The arrow etc. will show up in center display under tach when you have entered a destination for Navigation, and then tap your lower left computer stock to scroll through displays until the arrow shows up there. If there is no "active" destination in the Nav, the center (centre) display will say "Route guidance not active". Then you tap your computer stock to bring up something useful like TPMS or audio info.
Isn't it amazing that they made this system so complicated that many of us, most of whom are reasonably intelligent, can drive these cars for years and still not fully understand how they work? Maybe VW will help bring some sanity to this interface (although it appears the 997.2 took a big step in the right direction).

The TPMS on my Targa consistently displayed pressures that were about 3 psi lower than what I measured with my digital tire gauge. So I only had to drop 1 psi to trip a warning from the system, since it thought I was now 4 psi below recommended pressure. It was only useful to me as a relative indicator of pressure changes rather than absolute pressures. I'm almost glad my latest car doesn't have it so I don't have to look at false warnings on the cluster.

Ken - I will try the tip on showing the arrows, thanks.
Dan - Is CDS information activated via Durametric or PIWIS, or is it a PCM menu-driven command I have missed? I see song and artist info on my PCM display, but again, I don't recall seeing it on the instruent cluster...

As Ken alludes to, there is so much complexity to this that it can literally take years to figure all of it out. It's like learning Microsoft Excel or something!
I run 33/39 pressures all the time--Bridgestones, and with half a cargo load. Higher, and the ride is unbearable. (and I think my tire life suffers).
The CDS information could be menu driven from the PCM. I wish I could tell you definitively. You almost have to sit with another driver in a similar car and walk through the steps one at a time and coordinate as you go.

If you don't see the information that Edgy has shown in his photo's above, you're not getting the full functionality of your car and it isn't something that you, as an owner, can change. At least that's what my dealer told me. Take your car to the dealer and get it looked at.

It also gives some different displays to you.

Extended navigation takes over in areas where you lack digitized mapping. Also, you can run a trace mode--essentially dropping breadcrumbs on your route (so that you can repeat it again sometime). Handy for a variety of reasons to me.

997.2 TPMS seems to work pretty well on my car - for monitoring pressure or for indicating +/- pressure corrections. Although, I still use a digital gauge.

My .1 had it and I'm with you Dan - at first it seemed pretty useless but I did find it helpful on a couple of occasions. I recall though that it was pretty fiddly to operate.
