The Grenadier has its speadometer displayed on a centrally mounted multifunction display. If that’s not your preference a Heads Ups Display (HUD) is one solution. Here’s a cost effective HUD from eBay for less than £22 (AUD$42) The device connects to the OBD2 port in the driver’s side footwell and the cable can be concealed under the trim. A two way mirror sticker makes it easier to read on the screen.
