Had the trip computer out to fit leds when I have re installed it only get clock and speed alert, it I touch the select button I just get the time and date across the bottom in small print and cant get any other display until I turn the ignition off and back on. It did this when I first fitted it 2 years ago, not sure how problem fixed as went for a service and was working ok when I got it back, Don't know if they fixed or just coincidence, anybody have any ideas?

Mine did the same on Friday.
Simple fix!
Unplug the battery and leave it for a few minutes!
Reconnect and all should be fine.

No idea why mine did it, no mods at all... it just went blank and the OS and clock only worked

disconnected the battery fo 20 min no change still the same
