limit of kmz files on new Edge 1030 Plus?

I tested in depth now: the Edge 1030 Plus (I dont know if this is the case for the 1030 also) seems only to be able to work with 4 .kmz files. If one uploads more, only 4 are randomly shown on screen.

Moreover there seems to be a very low limit of overall size accepted by the Edge 1030 Plus: I tried to upload 3 .kmz files as custom maps
with 50 MB. This leads to result thath 2 maps are shown correctly and one map was only shown in parts.

tested with various maps - every tome the same restrictions: only 4 custom maps and only appx 40 MB overall size possible.

I do not understand this as the Edge 1030 Plus has a much faster processor as w3ell as 32 GB (!) storage.

Does someone have the same experience or give an advice how to upload better?

All would be OK if BirdsEye would be working for Edge 1030 Plus but as some of us posted here - they are not compatible (up to now?)

I have loaded three custom KMZ files totaling 27 meg. onto my new Edge 1030 plus. Those display properly. If I load a fourth kmz file which is 4Meg, it does not display. It seems to choose the files alphabetically. That is the non-displayed file name started with G, the displayed ones started with A, C and F. I which Garmin would up the limit. I'd like to have custom maps for all Vermont Counties loaded and displayed/ 

Garmin released Firmware 3.0 for this device solving the issues stated. Now BirdsEye works properly with the device and Garmin extended the number of tiles from 250 instead of 100 tiles.

Great and thank you, Garmin!!!

I have exactly this issue on my Edge 1030 plus, firmware 5.00. Uploaded 4 kmz files 10-30M each. It worked fine and I added 2 more and they didn't show up on map neither in the select map setting.

Names are formatted like this: 68000_5500.kmz.

The ones not showing was the ones with highest numbers.

I will try to rename them with letters and see if there are any difference.

Ok, please tell if it works. Maybe the colleagues from Garmin can tell us if the very valuable 250 tile thresholds is still existing.

May I ask how many tiles you can properly load and display?

Load 6 kmz files, added A to F in beginning of filenames. Now showing 3 maps, listed in order F, E, D.

This cause the some kind of issue I had with my 520, changing map files all the time but then it was forced by memory size or at least that was the assumption.

Tried Basecamp. At first "send to" stopped after 3 kmz, next try after delete it stopped after 2 kmz. Then I noticed a "limitation" message. "Cannot send Garmin Custom maps to Edge 1030 Plus (unit id xxxx)  (D:) due to the following requirements. Maximum number of images on device: 250"
Guess I need to start removing maps that I never will use then.

Then it seems to work properly and still have the threshold of 250 tiles.

Yes it is true - I also would prefer a tile-limit only defined by remaining storage on the Edge 1030 Plus. I don't know if this would be possible (can someone from Garmin maybe answer this?).

However I am thankful to have 250 tiles threshold at least.

I suspect the 250 limit is the space allocated for the tile list in "RAM" memory. Garmin might not use the remaining storage on the mass storage because it might run out of "RAM" if it did that. (There are other similar limits.)

This morning with fresh brain and some coffee I figuered out how it works with the 250 image/tile limit. For my trip tomorrow I need 4 kmz downloaded from a site with topo maps and they are around 100 images per kmz. I just imported them into Google Earth desktop and removed unnecessary tiles and it came unde rthe limit.
It's a bit annoying though that my Fenix 6 can accommodate 500 but memory seems as the plausible reason, but still disappointing.
