I had the same problem on our 2000 Odyssey and I ended up taking it to my local Honda Dealer in Erie, PA. They found a blown fuse, ran a "diagnostic" test to confirm everything was ok and removed the clear plastic lens and put the needle back on the Zero MPH pin then road tested - Total cost was $88. They did crack the lens removing it so it did require another trip to dealer to replace at no cost. My advice is let the dealer fix it. They thought some "power surge" was the culprit.

You can only adjust the speedometer with an ERA - Electronic Ratio Adaptor or possibly the Dealer, because the Speedometer is electronic.
We had the same problem...there was a recall on this...check with your local dealer.
I know the dealer ship scan tool can be used to reset the speedometer.
with the dealer computer.
Its an 07! take it to the dealer for warranty repair
You can purchase a "pig-tail" from the dealer and splice it in.
According to my dealer, no you cannot.
Need to know what is wrong with it. If both the speedometer and the odometer don't work, I would suspect the VSS (Vehicle Speed Sensor) located in the back end of the transmission is bad. If only the speedometer doesn't work, I would suspect the instument cluster has to be replace with a reconditioned one from your local Chevrolet dealer. Contact a dealer for a price.
See your local GM dealer for a reman swap.

Speedometer is ran by electronic sensor on rear end. Odometer is ran from speedometer. If both don't work problem is sensor. If speedometer works sensor is okay. If speedometer works and odometer does not problem is in mechanical parts (gears) of of odometer and has to be replaced. Can get used from eBay (search for speedometer or odometer, is one unit) or take to dealer.
