Just how accurate is the mph speed reading generated by TTM? Is the accuarcy effected by type of receiver used (I'm using a BT77) or coverage?
I know very few car speedo's are 100% accurate, but sometimes the difference in readings can be as much as 10mph. At other times is seems quite spot on.
Thanks. |

Your GPS speed reading is likely to be more accurate than your car speedo which is likely to be out by +/-10%. |

I would say that ttm speed reading is very accurate,it is your car speedo that is out.
I am saying this because i am a hgv driver and my wagon has just been in for its 2 yearly tachograph and speedo check,which by law has to be spot on.
when travelling now i cannot see any difference in the speeds shown both on the needle and display of ttm.
I am using the original ttm silver receiver. |

Tomtom's speed is usually about 5mph slower than my car speedo, so my speedo probably shows the speed as 5mph faster that it actually is.
It's no wonder I've never had a speedy ticket. _________________ Nokia 6600 running TT Mobile 5.0 |

The UK requires a speedo to be accurate or 'fast' -0%, +10% at 30 mph. |

My car has an LCD speedo display - the TT measurement mirrors it almost exactly. |
