I'm assuming the GPS is not powered when the key is off, which would lean me toward the speedometer being damaged internally.

Which would then lead me to ask how did it get pegged? Did something break in its needle mechanism, or did the GPS provide an erroneous signal that caused it to max its MPH and subsequently damage the speedometer?
