Hello,

Please forgive any missing information and clarity - my first post here.

I have a (free, primitive) website ("TrickTracks") that allows users to "drop" a gpx file onto a webpage and receive a garmin .img map file as a download. Under the covers my My web server converts the gpx file to an MP file and then feeds mkgmap (currently r4000) to produce the .img file. I've had this website live for about 5 years and it's been well received by my users. The users are primarily motorcycle and bicycle riders who create tracks for their rides and use the maps on their various Garmin devices. My software does a bit of "special" processing on the gpx files in that certain waypoints are converted to large polygon targets and the gpx track lines have mileage marker polygons added at the user requested intervals. There are various web-page configuration options, etc. that let users specify map line width, etc. This has worked well on almost all garmin devices for many years.

I now have a problem with some of the newer garmin devices (XT2 and Treads) where the labels for the polygons are not showing up. I'm looking for ideas on where to start with this issue. I have a few ideas and would like ideas on how to proceed:

First, is this a know problem in this community? Have the mkgmap/OSM developers already tackled this issues and has mkgmap been changed in some way to deal with it? I will admit I have not upgrade my server yet to the latest mkgmap.
I am assuming garmin changed something in their rendering software to now show labels that used to work (I suppose that's obvious). I have tried to see if there was a device setting that affected this but have not been able to find any that work.
Is there some limitation with using MP file input to mkgmap that will, in the future, hinder generating .img file for these newer devices. I do not generate and JOSM and have not researched that as it seems like overkill for my application.
Is there perhaps something in my TYP input to mkgmap that could cause this (I self generate TYP files on the fly but they have worked for years and still do on the XT, Montana, etc.).
As a side-note, the labels on my MP polylines do display correctly.
I can provide the MP file contents I am generating for the failing waypoint labels if that would help.

Thanks you for any input and help you can give me.

Scott
