The entire speedo has to come out of the car, then be dismantled to the bare PCB and 5 PLCC SMD LEDs will have to be swapped out. It's about 2 hours of work when you get handy on it... We've got a guy on our Dutch forum who does this modification and I've taken it upon me to redo OEM radio's in blue: This involves abit more work (about 3 hours), since there ar 45 "1206" SMD LEDs that need to come out and to get to 12 of them the dispaly needs to be removed, including it's 47 pins that need to be desoldered... I also "do" the light adjuster: (don't mind the color: blue is quite hard to photograph properly; the radio and adjuster are the same color as thee speedo you see above) We have talented people like Jan and EJS on our Citybug forum that are happy to swap the LEDs for the members. Thx Jan for the explanation. Guidom
