I do not get the tire temp displays etc. when using these keys...Any ideas would be appreciated.

Only F9 gives tyre temps.
Do you get the other F# menus of suspension display, brake bias and anti roll bar settings and the pit stop display?

Also good to know: Do you have a hud at all? Do you see the map in the topleft and your splittimes in the top right corner? You might have accidentaly switched the HUD off using shift+f.

Thanks guys for the replies.....I don't get any of the F9 to F12 menus but I am getting the map in topleft and split times.

You're propably using one of those keyboards with special keys mapped as a second function to the F-keys. Use the corresponding key to switch between the special functions and the F-keys. On Logitech keyboards that key is often called "F-key" (Desktop MX-set keyboard and others).

That did it Vain, thanks so much...on my keyboard it was called "F-Lock"
