I have a basic 2 line display with Temp / clock / radio ect . and wondered how easy it is to upgrade to a trip computer. as mine is a bit naff

I have looked at the spec from 2003 of my 1.8 Active Vectra and you could pay an extra £250 at the time of purchase to upgrade.

I have been looking around on ebay to see if i can get any ideas , but cant see anything.

My currant display is the square facia type with a small rectangle display (orange on black screen) with 2 adjustment buttons at the bottom.

on the spec i know they can change the display also for colour one if you have the NDC2013/2015 Sat Nav/cd/radio ect

Anyone out there have any ideas

many thanks
