FAO Tims Postcode Files

I have a Tomtom Go 300 which appears to hold the wrong postcodes against some addresses. Have tried to download postcode files but getting error with each file. Can someone help me resolve this problem.

What is the size if your zip folder? it should be about 8.86mb.

I think Chris is referring to the Postcode POI Files that were in vogue in pre V5 days.

@Chris, can you tell us a bit more of what your problem is, and what you are trying to achieve?

Richard,

On my Tomtom Go 300 there are a lot of areas particularly in Blackpool where the postcodes and addresses do not correlate. All I want to do is to be able to navigate using postcodes and house numbers? Is this too much to ask?

Unfortunately it's not as easy as that. Smile

The Postcode Database was originally built up to accomodate the Postal Rounds in the UK.

When Ordinance Survey decided to create a geographical database of Postcode Locations it wasn't as accurate as one could have wished for. It's original purpose was not for the use it gets now.

This means that if the 'centre' of a Postcode falls between 2, or more, roads the sat nav Device has to make a decision about which is the nearest road. After all we are talking about Road Navigation (generally).

I find that if the Postcode returns an incorrect road, it is easier to go to Browse Map and use Find | Address | Postcode to pinpoint the Postcode location and very often the road I want will be adjacent, and not necessarily the highlighted one.

A roundabout way, and not the best, but it works. Smile

I can then use Navigate to ...

Richard,

Prior to buying the Tomtom which I have now, I hired one for a week to test drive the device. As all the postcodes in question existed on the Tomtom which I hired, I thought the Tomtom which I bought would also contain the same information. How wrong was I? I believe that there are sites out there that you can download the corrected information, the one mentioned at the beginning of this thread is Tim's Postcodes. These are links to postcodes held by region. Unfortunately it throws up an error when trying to download these files? Thanks for your help anyway.

Have you tried connecting the device to Tom Tom Home & checking for updates?

May be worth posting your software version & an example of a problem postcode for others to check against.

I will answer the examples bit (I have my Chrystal ball working again)

FY2 0ST should be 339 Warley Road

FY1 2PH Should be 8 Woburn Road (it is using a Navteq map)

NG19 9BU 25 New Mill Lane, Chris - in the case of this last one do you travel their often? - if so has a Redlight camera appeared on the junction with Leeming Lane South

The Post Code data is refined with each map release, but it will take time, in the first example above you would have travelled down Warley Road so it gets you very close, the same applys to the third example. the FY12PH is fine if you switch to a NT map (something we have seen before TBH) - Mike
