Thanks for the response.
This is the ultimate plan once I've got a way to "talk to the car". Then I'll be searching for a "blow by blow"

I'm not that fussed about the the units on the Odometer. If it was easy to change I would have given it a go but it seems a bit of a minefield so I'll live with "Kilometers" The speedo looks like an easy fix just swapping over the tacho and speedo meters from the MPH binnacle. Fingers crossed,
.

Just get a sticker kit for the instruments?

Why would you swap the meters?

Cos he can't do the mental arithmetic to convert KPH to MPH, 50kph = 30mph etc etc.

that’s what I did, works fine. Don’t try swapping the dial faces for stick-on ones off eBay, just swap out the complete instruments.

Not recommended. The two-teaspoons method of removing needles just wrecks the instrument.
And the preset goes wrong too. I know….
Instrument modules are cheap.

Because it's easy. Whole job took about an hour. Replaced the tach and speedo gauges from another binnacle (cost around £25 from ebay) and the job's done. Worked perfectly and checks out accurate against GPS without any calibration.
The speaker on mine had given up the ghost as well so that kind of forced my hand.
