Agreed…but I’d personally get one of those nice double din Kenwood or Pioneed Navi’s that allow you to setup gauges (if you wire it as so) and use that.
Or go baller and build a carputer with full OBD intergration and parameter readouts.
But that’s just me. You probably saved a whole lot more money going this way :lol.
+1 for being handy though.
