I wanted an outside temperature guage and a trip computer too. The HSE dosn't have anything like that either.
LR were not exactly at the forefront of driver info systems when they decided what to fit to the FL1s. My 1982 BMW had masses of stuff which even BMW no longer fit on current models.

I put over 350K on it so grew accustomed to an 'excess' of info and now misss having it.
I now have a 'Scanguage2' fitted permanently wired into the OBD socket on the Freelander which gives me a choice of 14 guages as well as a trip computer. It reads codes and can clear them too. It sits neatly at the bottom of the dials in front of the steering wheel.

I've also got a 'Wayfinder V7000' - which incorporates an altimeter, compass, and an inside/outside temperature guage which is usually fitted to gliders, which is pretty good. A bit over the top for most folks, but I like it.
