Roadster Trip Computer Fitting

Heres the guide to fitting the trip computer to the roadster

Modification Details

The 2020 Problem

For some reason, smart didn't code a dynamic date code format into the trip computer.
Instead, it limited the available dates between 2002 and 2020. So after 2020, the date will be wrong.

However, if you want the day and month to be correct, you can choose a different year.
Obviously years can only have 365 or 364 days for a leap year.
If you want the day of the week to be correct then just substitute for the following years.
Actual Year Substitute Year
2021 2010
2022 2011
2023 2017
2024 No available substitute*
2025 2014
*2024 is a leap year and they only repeat the same days of the week every 28 years.
That means the next previous year was 1996 which isn't an option on the trip computer).

The Trip Computer

The Roadster trip computer is an addition for the roadster to include information
like mileage / speed etc, you can find more information here.

To be honest, it's not worth bothering with.

If your Roadster has the boost and coolant temperature pods installed and working, then this will just work,
if you have no pods then it'll still work but you will need to go hunting for the wiring connection.
It's usually taped up to the wiring loom behind the stereo but can be anywhere behind the centre console.

You need the following parts to get this working. You buy these parts from smart.

SQ0013120V002C59Z0 trip computer
SQ0013157V004C22A0 switch face
SQ0013156V004C96A0 switch frame

Button Relocation

Basically we are going to move the button bank down into a lower drawer and install the trip computer in its place.

Remove your stereo, and custom surround if you changed from the original, there are 5 clips
on the original face, 3 top and 2 bottom, releasing the top and pulling and the facia will pop off.
