This site that BorisM posted allows you to download preconfigured .KML files which as we all know is the format that AVIC FEEDS converts files to in order to be read on the F series. However, being these files are already in .KML format, you dont get the ridiculous 300 locations limitation you get with AVIC FEEDS. I have tested it with the Starbucks file and it does work. All 11,000 plus locations appear in the POI list on the F series. The only thing I haven't figured out yet is how to integrate a custom bmp image for the icon but Im sure someone will post a solution soon. There is a seven dollar registration fee to be able to download .KML files but for me it is well worth it.
UPDATE: On further testing and the findings of forum member njohnston this solution does not address what I thought in the above thread. It appears that the limitation is not only with AVIC FEEDS but also with the F series reading from the SD card.
