Q: Can you explain the chart numbering system


A: This is explained at the bottom of the Chart List section




Ordered charts but not heard back from us? Check your spam folder—very occasionally our emails are diverted by your security software! If there is nothing there then please email—see Contact


Your chart download is constantly interrupted. If this happens it is likely to be because your computer’s power saving settings send it to sleep too soon after the last mouse or keyboard action. To adjust this, click on: Start (bottom left of screen): Settings: System: Power & Sleep. But if it is interrupted you can just click on Resume.


You are trying to set up the charts but keep getting an error message ‘This page can’t be displayed’ or something similar. This will almost certainly be because you have not unzipped the zipped folders we sent. Please refer back to the Download Instructions or ‘First steps  - Please Read!’ note that came with sets sent by post.


You’re are trying to unzip a file but get error messages. This can be because the file path is too long. You need to put our material either directly onto your ‘C’ drive or into one of your main directories such as ‘Documents’. There can be a temptation to put it into a sub-directory of ‘Documents’ (e.g. Documents/Sailing/Charts/UK/Scotland/AntaresCharts/….) but if there are too many sub directories, as in this example, it will fail to unzip.


Other problems with setting up the charts? There are detailed instructions, setting-up guidance and lots more help in the Commentary that comes with the charts. As a last resort, but only as a last resort, please do contact us by email—we don’t like people to give up—if there is a problem it is usually very easily resolved.


Helping a friend to install our charts on their iPad or iPhone using your PC or Mac. This can cause problems as the devices tend to sync when connected together. A friend of Antares Charts has found the solution: a very simple note can be downloaded here.

Android devices: extra SD cards. On an Android 2.2 device with extra Micro SD card, after connecting it to the computer we had to enable access to the storage by going to the ‘Notifications’ area (hit button on device that is at the left hand end of a row of buttons or bottom of a column of buttons) and then ‘USB Connected’ then ‘Turn on USB storage’ and then ‘OK’. You should then be able to find the device’s storage on your computer, which should have been allocated a letter on your ’My Computer’ screen, alongside the device itself. Then go back to the paragraph above for instructions for copying the chart folder...

What happens if I don’t delete all the old charts? Where a chart has been expanded or changed in any way Memory-Map won’t know which is the latest so you can’t be sure you will see the most recent one.

What happens if I delete some or all the Marine (UKHO) charts by mistake? If you installed Memory-Map correctly and if you have not removed the link to the Marine (UKHO) charts in the ’Refresh Map List’ dialogue box it will automatically replace any you deleted when you click ‘OK’ in the ‘Refresh Map List’ dialogue box.

What happens if I accidentally removed the link to the Marine (UKHO) charts folder from the ’Refresh Map List’ dialogue box instead of the link to the Antares Charts?  You need to find where your UKHO charts are stored on your computer and then ’Add Folder’ in the ’Refresh Map List’ dialogue box to re-create the link. Memory-Map tell you to install your charts directly onto your ‘C’ drive  - our link (path) looks like this but yours may appear differently:

C:\Maps_v5 and the box ’Search sub-folders’ has been ticked.


The Marine charts are in a sub-folder of Maps_v5, namely \DMS\charts\UK_2019 (or C:\Maps_v5\DMS\charts\UK_2020 if you are reading this after March 2020 and have bought the latest charts). But because you have ticked the ‘Search sub-folders’ box it will load all charts in any sub folder of Maps_v5. For the same reason it is essential that you remove any old charts from Maps_v5, whether ours or Marine (UKHO).
