Switching ODO to miles from km

[nummish]

I bought an MSP protege in canada a few years ago then ended up moving to Texas. One of the requirements for legally importing the car (now that I want to sell it) is to have the ODO display in miles as opposed to the default km from Canada.

Is there a simple switch to flip for this? or will I need to get the dealer to replace the dash assembly?

Buy one on E-Bay that is MPH. 5 Bolts and you are done.
