TomTom Phantom Road that won’t disappear

February 26th, 2010 No comments

SatNav maps are only as good as the map data on which they are based. Inevitably errors will creep in and roads change. TomTom GPS units have a feature called MapShare which ostensibly allows you to report any such errors to allow the maps to be corrected.

Since I got my SatNav five years ago, TomTom has shown a road in Horwich that has never existed. Unfortunately, despite reporting this error using MapShare (and prior to that directly to TeleAtlas, the map provider), this road is still shown on TomTom’s maps (updated today v845.2666):


This may well be a phantom road – a deliberate mistake put there by TeleAtlas to catch out anyone who decides to copy their maps. The problem is that the TomTom will try to use this road as a route. SatNav units often come in for some stick when they route drivers down none-existent roads, but if the suppliers fail to fix these errors, despite being told about them several times, it is hardly surprising.

Haydon Bridge Bypass Complete (according to Google)

November 18th, 2008 No comments

Haydon Bridge is the last remaining village on the A69 to be bypassed and while construction is still underway with a completion date of Spring 2009, Google maps appears to have jumped the gun and seems to think it has been completed:

I have just updated the maps on my TomTom and the new bypass is also shown on here:

Haydon Bridge Bypass on TomTom

This is not surprising as both Google and TomTom take their map data from Tele-Atlas, who would appear to be the ones jumping the gun here.

Ironically, TomTom’s map update service proudly claims “Tomorrow’s maps today“. I didn’t realise they meant literally.

Further Update (24 Nov)

A representative from The Highways Agency has today confirmed that they were unaware of Google and TomTom showing the bypass as open. They also noted that Google maps has given the old road the number B6319 (as have TomTom) which has yet to be confirmed.

Update (27 Mar 09)

I drove along the A69 today and the bypass is now open.
