Quoting Andre Hinrichs <andre.hinrichs@gmx.de>:

Hi List,

I'm just working on a specific style which shall help me mapping some details when I walk around. E.g. I'd like to have an icon for traffic_signals and different icons for emergency_phone/telephone and different icons for post_boxes with collection_times and without collection_times. Otherwise it's really difficult to see whether I have already tagged some details or not.

I've searched the current cGPSmapper-UsrMan-v02.5.pdf for assistance but could not find any codes which I can use for custom needs.

Question: Will I get problems if I use codes which are not listed in the document or is this just unknown? Or are there even codes which are reserved for custom needs? There's a gazillion POI Garmin types available, but only a couple of hundred are distinct icons - so you get a lot of repetition. As far as I know, you can use any POI type code you like, combine it with the corresponding style file entry to assign it to a given OSM tag, and then use a TYP file to give it the symbol you want.

FWIW, I'm (slowly) putting together a spreadsheet with each type code and the corresponding default symbol (i.e. how it appears on the GPSr unit when you're not using a TYP file). To do this I wrote a little app in c that outputs an OSM file containing a regular grid of POIs with an associated points style file that assigns a unique type code to each node. It can generate an arbitrarily large grid of POIS. At the moment I'm working through the first 10,000... :) -- Charlie
