Hi, I have bought a satellite navigation unit for my toyota land cruiser colorado?

It was originally took out of a land cruiser amazon, is the wiring loom the same as it is in the amazon, or will I have to dewire my whole colorado to get the navigation system in?|||These are not common cars, so your best bet would be to ask a dealer. Does the connector in your Colorado fit? If it fits, I'd go ahead and try it. It would be unusual for the company to use two separate wiring schemes but ask a dealer to be sure.
