just finished installing custom POIs into 2011 300c with 8.4n radio and it was a tedious task
i thought i would list the needed steps to help the next person out
1--- use a memory stick-not a sd card or disk
2--- create a folder named Garmin important note this is CASE SENSITIVE
3--- create a sub folder named POI also CASE SENSITIVE
4--- use garmin poi loader to load files into this folder this file must be named Poi.gpi and is also case sensitive.
5---- start vehicle let radio boot up and install memory stick and follow directions on screen
hope this helps someone out
