Has anyone had any experience with the speed on their GPS "doubling". Essentially if going 35mph the GPS says you're doing 70mph, 45=90, 25=50 etc.
HDS 9 Gen 2 touch, running what I believe to be the latest software, but it's my buddies unit so I don't have it to pull version off of. I am however the one that updates the software for him when available.
Anyone seen this before?
Thanks!
