Ok, I'm driving and turn on my gps for the first time and the speedo says i'm going 5mph faster than the gps does....is there a way to adjust this, I have stock tires and wheels, they are 185-60-14s,
I also compared to my wifes hhr while driving and she still said we were going 5mpg slower than what mine was showing...
Just looking to see if there is a way to calib this or do I need a new speedo gear

 

eh lol mines off too. by like 5 as well.

 

GPS MPH is always a little off

 

yeah, but I made sure and bounced it off of my wifes newer hhr...so that's two against 1

 

mines over 5 too, itll say im goin 60 and when i go thru the construction zones and they have the speed traps, itll say 55. i like it like that tho. thazt way when i see a cop and slow down then im always going under

 

I'm not such a fan, it throws off my mpg calculations, towards the not so good side, that's my main issue, oh well I guess there's not too much that can be done other than get a bigger tire or change the speedo gear out

 

its only 5mph tho, just minus the 5

 

Its your stupid GPS not your speedo most likely.

 

gps's r known to lag a lil but hondas speedos are also known to add on 5mph

 

I think it's the opposite
