v845 PostCode data Download Link

[PaulB2005]

If i enter a postcode such as

AB12 3CD

with the 801 postcode database supplied with the unit it would take me to the right road, say Wright Road, London.

With the 840 and 845 postcode database it take me to

Wrong Road, london

which is 2 streets away.

Entering Wright Road works ok, but not off the postcode anymore, unless i revert to the 801 Postcode database.

It was annoying when the map insisted the house numbers ended at 140 when there are 190 houses in the road. Finally got that sorted now they mess this up.

I can't work out how this PostCode file is suppossed to work with the map. When i bought the device the supplied maps wouldn't bring up my road using the postcode (neither would my uncles v out of date TT last month) until i got the latest map off the LMG. Since then i've only used the 801 PostCode file but the latest maps.

How does the information in the 2 relate to each other? i.e why do some corrections appear when the map is updated and some when the postcode file is updated?

Thought they seemed smaller for the .ver files.

Who cares what HOME tells you anyway! You should know what version of what is installed - never rely on HOME!

Thanks, Everyone for the great information supplied. Just bought a TomTom One XL IQ Routes a week ago and updated to the latest version of maps via TomTom Home, and foolishly thought it would also give me the latest postcodes as well. Checked my version of the postcodes file to find that I had version 801. So have down loaded the 845 version and installed onto my TomTom without any problems. Thanks again for the information.

Yes, very many thanks to all you ever helpful contributors.
My new Go 730 would not ‘do’ postcode search after updating to most recent map.
After reading this thread I managed to discover that my “zip” file only had Dutch postcode data!
I inserted the v 845 G.B. data from the link and now all is well.
Brilliant!
May I request that some mitey brane applies himself to the problem of making the enormous amount of expertise available on these forums more specifically indexed and easily searchable?
When you don’t really know what you are doing, it is easy to take a hammer to the device when what you really need is someone to guide you to a mallet!

I've been searching the internet and these forums, but cannot find an answer to my postcodes problem - sorry if this has been covered before, but I can't find it if it has!

I'm due to go to Jersey and Guernsey for business soon, and my maps seem to cover the islands adequately. However, most of my business takes place in Garden Centres, which don't tend to have an address, just postcodes.

Now I'm sure that at one point our TomTom One XL used to have Channel Islands' postcodes - however, since updating to newer maps, this no longer seems to be the case. You can search by road names, but not postcodes.

I've tried copying back the original "zip" folder contents to the device (701), to no avail; I've tried various other postcodes files (607 and 845), still no joy.

Does anyone have a postcodes file that covers the Channel Islands or know where I can get one? Any help would be greatly appreciated

As there is no way to 'read' the area covered by any particular postcodes file version, can we do it another way by you giving us a couple of examples of Channel Islands postcodes to try?

[DarrenR21373]

Good idea, here's a couple that I'm 99.9% sure were once available:

GY5 7SS - Le Friquet, Castel, Guernsey

JE3 7BP - St Peter's, Jersey

Something else that I seem to remember - the One XL didn't have a "zip" folder at all at one point (despite being bought brand new from a reputable shop), even though the C.I. postcodes as well as all the other UK ones worked. I remember this because I wanted to copy the working C.I. postcodes to my old TomTom One 3rd Edition. Is it possible that they were somehow hard coded to the original map?

I also seem to remember that we had no postcodes at all after subscribing the XL to the new map service, and the 701 file possibly got copied from my One 3rd Edition...

Thanks again.

IIRC you only ever got the 3 Digit Postcode for the Channel Isles - Data that is built into the Map, rather than the zip add-on.

Went to the link and downloaded to my TT920. My zip. properties is now showing 21.mb but the update is November 2007. Opened the zip folder on my TT and it is showing 2 files for Great Britain and 2 for Nederlands dated 2007 and compressed zip of 10 mb dated to-day. I thought the new one overwrote the older ones ? Should I delete the old ones and does the zipped file automatically unzip to the TT. Sorry if this does not make sense but I am not super techie. Is there anything else I should be doing?

Connect the device to the PC and use Windows Explorer to view the contents of the "zip" folder, in it you will find four files, fight click the file named"Great_BritainPostal.ver" and select Open With/ NotePad, if you have the latest version as of today (v845) you will see the following in NotePad:
