I’m planning to import a 2015 Toyota Prius from Japan and understand that for UK registration, I need to make modifications like installing rear fog lights and converting the speedometer from kilometers to miles. While the speed can be easily switched to miles with a button, I’m trying to figure out the best way to convert the odometer reading from kilometers to miles.

From what I’ve researched, one option is to replace the entire speedometer cluster with a second-hand UK-spec Prius cluster, which costs over £100. However, I’m wondering if there are any alternative solutions. For example, is there a software reprogramming option or a cost-effective aftermarket solution that can handle the conversion?

I’d appreciate any advice or suggestions on how to approach this.
