No Post Codes Accepted

When I put a post code in my Tom Tom oNe Excel it only gives me the first part. How do I find an address using the post code and how can I get it to accept the full thing?

Have a look at whats on the device using Windows Explorer, try to locate a folder named "zip" (without the "") if thats present is there anything in it?

If nothing is there you can update your postcode data by clicking the following link:

Extract the download straight to the drive letter associated with your TomTom and you should find the postcode data returns - Mike
