Tried out Waze for the first time today in the new truck. At highway speeds, Waze is reporting 10 - 12 mph higher than the speedo. Truck is bone stock.

When I unplug the phone cable, Waze speed matches the speedo.

Anyone else seeing a similar issue?

 

It is a known issue with iPhone, Waze, and Sync3.

On Android it is correct but tends to not search for locations....

 

Ok, thanks. I did a search on Waze before posting, just missed that thread I guess.
