Hi Peter I'm off to Ally Pally on Sunday, for the Classic and Sports Car show. I was thinking of dropping into Hyde Park to see the send-off.. The dials and GPS etc are really easy. You can get a very cheap OBD2 sensor from eBay, which plugs into the multi-connector by your right knee (behind the big rubber IVA grommet unless you've removed it!). This talks to lots of phone apps (I use one called Torque), and send the engine data straight to the phone, along with GPS data. On the Goodwood track, I put this into a PC add called RaceRender (free unless you want a fancier version), and this ties the video, the OBD2 datra, and the GPS data altogether into one. You can even add a different soundtrack, multi camera angles etc etc etc...! Took a few minutes' thought to work it all out, but it's very useful. All the best Ned
