http://www.roadstermodelguide.co.uk/Accessories/Trip_Computer.html I purchased my Smart Computer from Smart in Tonbridge along with the two switch panel parts which you also you to replace when relocating the switches. I had only a few pence change from £200. Here are some pictures of the computer, my poor car in bits while I fitted it, and afterwards the finished result. Is it worth it? Yes! Can you fit one yourself? Well yes, so long as your comfortable with fitting car hi-fi's and speakers; FQ101 has instructions. There are other warnings it gives but I can’t get pictures without causing the faults: Engine temperature too high, oil pressure too low, brake fluid level, etc.
