who do you trust?

[Mells]

the speed on your satnav or the one on the speedo?

me: car

 

[Laura]

car becuase it says im goin faster

 

[biojo]

the sat navs better for the average read out, but personally i wouldnt go off it for speed limits near cameras, better to be safe then sorry

 

[Fletcher]

Speedo everytime.

 

[aaronc]

Car speedo is normally 2mph faster than actual speed.

 

[derv]

on the toyota van i use for work, anything over 40mph reads 8mph higher on the speedo than it does on my tom tom, and my origin b2 which both show identical speeds

 

[Mells]

mine seems to be anything upto 5mph out. its worse at slower speeds, which is odd considering the faster you go the more a variance is likely to me magnified.

 

[sneeks]

I trust the sat nav more but I always use the car speedo anyway.

 

[edde]

Neither.
Sat nav only works on the straight to be totally accurate the speedo about 5mph out so I just worked out what the true speed is by knokcing 5mph off the clock speeds.
After checking though the affects of tyre wear on the speedo (after all a smaller wheel near the limits doesn't travel as far per rpm as a new tyre) I'm not worried about it being out as I couldn't find any real difference.

Sat Nav.

TomTom reads exactly the same as my RA2.. speedo's are way too poor, heh.

 

[TELFORDS_LURK]

My Origin B2 and Pioneer AVIC-X1 Sat Nav both read 4mph slower than the Speedo, but use the speedo anyway when going through speed traps just to make sure I'm not gonna get stung.

I do bit of both even tho my speedo is pretty damn accurate compared to my gps - almost nothing in it sometimes at higher speeds

 

[clio__chris]

sat nav but i go by the speedo speed just to be on the safe side

 

[H182]

sat nav but i always go off the speedo with speed cameras as its about 3mph slower than the sat nav says.

 

[KyleB]

again sat nav, but habit just dictates me to use the speedo
