Map shown has incorrect post code

I am re-designing the web site for www. alanco-alamatic.co.uk and am currently hosting the revised pages on another domain namely www.villa-amarillo-sol.co.uk

I have obtained API references for both domains to show Google maps.

If you visit contact1.htm which has its own API (different from www.alanco-alamatic.co.uk's) the map is indeed showing a map of Manchester U.K. but it is showing the Post Code (zip) as M8 NOT M34 3WH. It follows therefore that the pin is not showing where their factory is actually located.

Have you any idea why Google Maps choses to show M8 when the post code of M34 3WH has been inserted as the correct parameter for the post code?

I have used your Google Maps extension for a couple of years now and have to say I do not find it produces accurate results - which rather defeats the object of my using it. This applies whether you insert physical addresses OR a location's co-ordinates. It is a disappointing extension that clearly needs far more work doing on it, if it is to be of use to web designers. Cannot advise anyone to buy it as it stands.
