    I'd very much like to completely purge anything on there and put it back to factory defaults but I'm not sure what can be deleted !
    Search for files with extension *.img in folder:
    on Nuvi - .System and Map,
    on SD - Garmin and Map.

    Single copy of gmaptz.img and gmapbmap.img is system files. All others *.img files is optional maps and you may have a conflict, for example the same maps of other version or overlapped maps!

    I am having a similar problem after updating the firmware from 4.30 to 4.40 in a Nuvi 755. I cannot calculate routes for locations outside the US 48CONUSA. I have tried to calculate some routes in Panama (between two locations) using the SouthAmerica 2012.40 map and I cannot do it. However, I can calculate routes within the USA using the NorthAmerica 2012.40. Before the upgrade I was able to calculate routes without any problem using different maps. I have tried many of the suggestions mentioned before (re-installing maps and different versions of the firmware) but it is not working. This is a puzzling question that I would love to understand and maybe solve.


    EDIT:
    As I said in a previous posting, I had the same problem after updating the firmware to 4.40. I contacted Garmin and they made a lot of recommendations but I could not solve the problem. I am TomTom user (I do prefer the TomTom GPS since it is more "user-friendly") but I have a Nuvi Garmin (755t) that I use when I travel to places where I cannot use the TomTom.

    I spent about a week dealing intensively with this problem and doing many things without being able to solve the issue. I was convinced that something got corrupted when I did the update and the problem was to find what file (or files). After many deletions and changes I think I found the source of the problem. The original NorthAmerican maps (both the regular and the 3d) plus the JCV were corrupted. I deleted all the img files and all the JCV files and I only kept one map (the one I will be using in Panama) and it is working again. I renamed that map from GMAPSUPP.IMG to GMAPPROM.IMG and now it is working fine. I can calculate routes in Panama and do all the things that I could not do before
    like creating custom routes in advance.

    As I said, I am not an expert on Garmin software or hardware and I solved the problem I had by trial and error until I found the source of the problem.

    Hi,

    I am not sure if the OP had solved this, FWIW I had a friend with a similar problem on his Nuvi.

    I was able to solve this by loading the appropriate Basemap on to the unit.

    Hope this would solve it for you.

    Maybe some corruption on Nuvi Internal Drive or Memory Card ?
    Maybe a corrupt file ?
    Maybe a corrupt Flash Region ? (Not so easy to fix)

    Perhaps someone can help me out, too,

    I updated my garmin 765T unit. New firmware (v4.50), new Maps (For example Garmin City Navigator Europa NTU Unl*** for 2013, 2014, 2015, 2016 as gmapsupp.img), basemap 501 and removed the old gmapprom.img.

    I even tried older firmware versions 3.60 and 3.90.

    The problem is, route calculation works until 99%. Then it says "cannot calculate the route."

    What I've also done was updating the TMC Messages for Germany. It is really weird. All the necessary files should be in there. I even tried it with a sd-card. Attached you find the current file-structure.

    I realized, that when I open the map with my unit, everything works quite slow. Zomming out takes ages. Route calculation is not possible for locations within the same town.

    Thank you for your support.

    How much is your free memory on your unit?
    If you have less then 100Mb or GPX folder larger then 20Mb, then here is your problem.

    Do you create hard reset?

    Free memory is 1,8 GB. I already reduced the map to Germany only. GPX was 19 MB. Deleted archived data. Hard reset did not help me.

    It looks like your basemap is faulty, try to replace it.

    This unit drives me crazy :-/ I already had this basemap with the same size. I replaced it. Tried it again: Cannot calculate the route.
