Hey all,

I've been looking out for an OBC to retrofit my crappy digital clock/temperature one that is currently in my 525i. Wreckers here in Australia are asking about AU$170 for one that looks like it's been ripped out of an interior with a crowbar, so I decided to browse in eBay (UK, AU has bugger all for the E34) for one.

The only question I have is does anyone know if the UK ones would suit the ones that came with them fitted in Australia? For example, the UK usually calculate fuel economy in MPG (just like in the US), but in Australia we do it L/100km. Would I be getting weird readings if I fit a UK OBC into my Australian car, or is the method of calculating economy toggled by the km/mile switch button at the top left corner of the unit?

I was thinking of getting one from the US, but the labels of the buttons are all "American" (MPG etc), and I want my unit to be as close to the Australian spec as possible.

Anyone got any ideas? Am I worrying about nothing?
