How to find out which areas of a town are VM cabled

I can't find anywhere an approximate map showing where VM cabling has been installed in some large town like Exeter or York, the ones where SamKnows says

Cable Broadband Availability
Virgin Media: available in some areas

Can anyone point me at such a series of maps, please?

Obviously it could be done on a highly individual basis by plugging in a series of postcodes, but I'm hoping for a map!

Thanks, Andrew - I never knew this existed, even on your website!

Am I right in assuming the the light green squares mark the location of VM cabinets? That seems to be the case for my town (although 'my one' is actually on the other side of the road!).

The green dots are postcodes where it is believed service is available but the density of virgin cabinets means often a similar correlation

Thank you again; in my case the usual place they put the postcode marker almost exactly coincides with the VM 'green cabinet'.

It would be nice to be able to click on a green dot and have the postcode displayed (that shouldn't take long to do!!).

Way down the priority list for now, and that list is pretty darn long as cannot afford a team of people to do all the boring implementation stuff
