Map Updates and Space


I am new to the Montana 700i so please bear with me. I think I updated the City Navigator map in the last few weeks and now my device seems to have hardly any space left on it. Garmin Express now says there is an update for the TopoActive Europe and when I try to install, I get the 'There was an error installing the update.' When I review the logs, it seems there is not enough space to install the update although it suggests the updated map requires significantly more space than the old one:

Not enough space for UniversalMapUpdateOperation transfer. Needed: 905115096, Available : 352616448, Reserved : 0

So my question, am I supposed to remove a map before I update it? Should I have removed the CN map before updating and should I now remove the TA Europe map too? Obviously what I don't want is to lose those maps altogether.

Thank you in advance,


  • Did you use Express to update the CN map? If so it should have deleted the old one but it's difficult to advise based on what you say. Are you able to list what is in the Garmin folder on your Montana?

  • Hi, Thank you for your reply. I'm not sure what's going on now. I have CN 2021.20 and TopoActive Europe 2021.10 and apparently both maps are up to date. Is there any way of finding out what the latest versions of maps are supposed to be? I tried to move the TopoActive map to the SD card using Garmin Express but despite trying three times, it kept failing with no meaningful error message.

    Below is an output of the Garmin directory.

  • Not sure from that list but you appear to have 2 maps installed on 1 May, is your CN map the Europe one? That map is split into 2 as per the 2 large .img files listed. You also have another map installed on 7 May, that is almost certainly the TopoActive map you previously had issues installing. This can be confirmed by running JaVaWa's device Manager program

  • Thank you. That website looks very promising with a lot of useful information and links. I will have a play and see what happens.

    I noticed you posted many times on this forum, helping people. Thank you for your time and sharing your knowledge.

    All the best.

  • Everything looks normal using JaVaWa. The two CN maps are two different regions of Europe but there is some overlap. I think to free some space in future if I need to, I can change the map region in Garmin Express.

    The option to update the Topo map no longer presents itself so I'm not sure why that appeared and now it doesn't. I'm on version 2021.10 which I understand is the latest version.

    Thank you for your help.
