I am wondering if anyone can help. I recently bought a 1999 406 GLX HDi 110. This model does not come as standard with a trip computer giving info on fuel economy etc. Does anyone know if it is possible to fit one of these to the car? Is it a case of changing the display unit to one that incorporates the trip computer? My other query is about cruise control. When I bought the car - the guy in the garage said he knew that this could be fitted for around £300. Does anyone know of this or heard of anything similar? Thanks in advance.
