Currently I have an '04 F150 XLT screw. The dashboard instrument cluster is the standard unit showing the basics including temp and compass. This was a mistake on my part. I felt that the expanded instrument dashboard (ie. Lariet, FX4)wasn't warranted. Are there any 3rd party devices that can be wired as such to provide mileage type calculations. Or rather is there a procedure to replace the instrument package with the upgraded one? (Assuming I can even get it from Ford.)

Thanks in advance.
