Latest Topo Maps not compatible with Basecamp

Just want to check that it's not my system:  Normally I can view any Garmin Topo Maps on my devices by connecting them to my PC and loading Basecamp.  It's a very slow process but does work.  I've just downloaded 2 of  the latest maps (Hong Kong and also China) and I now get an error saying there is an issue with both the maps.  This happens on my D2 Mach 2 Pro and also on my H1 Plus.  Loading the maps from SD card doesn't work either.  My other maps are all fine and the devices can use the new maps without issue.

I am aware that Garmin don't support Basecamp anymore and that this was bound to happen eventually.  Have the map file formats changed recently?  If they have I'll stop trying and find alternative maps as I use Basecamp for all my planing as I can't stand the lag and latency of the online Explore site and my fingers are not nimble enough to use the smartphone app!

  • Sounds like maybe your Basecamp's "card product cache" folder is corrupted/confused. This can happen periodically, especially when using multiple devices containing maps with Basecamp.I've had this happen numerous times and the procedure below has always corrected it. To clear this cache and re-index the maps on your device(s) to use them with Basecamp:

    Windows

    1. Close Garmin BaseCamp completely.
    2. Press the Windows Key + R to open the Run dialog.
    3. Type "%userprofile%\AppData\Local\Garmin\" (or copy/paste it) and click OK.
    4. Open the BaseCamp folder.]
    5. Right-click on the CardProductCache folder and select Delete.
    Mac OS X:
    1. Close Garmin BaseCamp completely.
    2. Press Command + Spacebar to open Spotlight search.
    3. Type ~/Library/Caches/com.garmin.BaseCamp and open the folder.
    4. Drag the CardProductCache folder to the Trash and empty it. [1]

    Next, connect your device(s) and launch Basecamp where the maps will now re-index (it will take quite awhile) and be available for use.

  • Hi, thanks but I've tried that already as it happens to me every now and then as well.  I just loaded a new map of a different area and it was fine.  Looks like it just affects the China and HK maps.

  • There was an issue with one of the Europe maps not displaying.

    I brought up the issue to Garmin. They looked at it some but never resolved it.

    Depending on what you are doing, you might be able to use a map from one of the many alternative providers of OSM maps in BaseCamp. These maps are often free.

    I use maps from bbbike, for example.

  • I use Talkytoaster for most of my maps as they do specific Basecamp maps for everywhere.

  • Yeah, I saw you figured this out. 

    Hopefully, the info is useful for other people. 

    (I doubt Garmin is going to address the problem.)
