my frontera rs sports speedo has stoped working?

I also have a frontera sprt RS I think mines a 98. The speedo also doesn't work, we sent it to a garage & they replaced something on it (that cost £180) & 6 months l8r it doesn't work. Wot I do jst for police & cameras etc is press and hold the reset button & it shows my speed, sometimes depending on the way you press it, it catches & it'll continue to work till I turn off engine. Weird eh?
