Rover 75 Club - New Instrument pack/trip computer retro fit. Help needed.
I've just bought a new instrument pack for my 75. Its a club model and is fitted with the basic clocks with warning light display. The new clocks have the lcd dot matrix display at the top.
I fitted them this morning and all the pictorial warnings seem to be showing correctly in the display (glow plugs, doors open etc). The rev counter, speedo, fuel, trip, coolant temp and outside temp gauges are working fine. My only problem is that the mileage is showing as 999999. On replacing my old clocks the mileage goes back to normal. Also, the auto gearbox "selected gear" display is active on the new one, my old pack has this but it is not illuminated.
Can anybody give me any pointers? Do I need to have the new clocks coded to my car with testbook? My workshop manual doesn't say anything about this.
Thanks in advance.
