Weird speed indication on 7200


I was in Southern Illinois last weekend with both my 7200 and Nuvi 660 on the dash. For about two miles the 7200 was indicating nearly 90 MPH while the Nuvi and my auto speedometer were showing my actual speed of 58 MPH. Anyone else experience this?

Nope, can't say that I have.

Normally when pushing 60mph

Normally when pushing 60mph on the highway my C330 reads 58mph. However I noticed where you reset your Trip and Reset Max option, that the maximum speed reading is sometimes whacky and on mine sometimes post 150mph or 170mph.
Now that is weird lol. I don’t think my car has ever done more then 75 lol.
