Speed -1

[jwurtz]

OK I have a wierd one for everyone. I have updated the speed on my local streets show they they show when driving. The problem I'm having that instead of saying 35 mph it shows 34 mph. So I will be driving along and I see 35/34. I have tried entering 36 and other numbers trying to get the system to adjust but it wont.

TT support says to check your safety setting and their is not thing. They have no clue. Has anyone else come across this?

Thanks for your help.

I have same issue on my GO 720. Also happens w/ setting a speed at 45 mph.

It is a well documented bug in the speed algorithm that takes mph, converts to kph, and then back to mph -- with the results you observe.

I sincerely doubt that is the reason. You change the road speed to 45 and it shows at 44 mph. 46 mph shows as 44. You change it to 47 and it shows as 44. This is obviously not a simple unit conversion error.
