Thread: Can Garmin Nuv i205 work with gdp files?

Hi

I have a Garmin nuvi 205
I understand that for maps for this model, we use gmapsupp.img
For world map, its gmapbmap
For POI , its gpi files

But what is gdp files? now of days some maps posted re in gdp format. How to i use or install them to my Nuvi 205?
I understand that i require mapsource but what file format will appear when i transfer to my device

Another question is, as the POI files are in gpi format, how do i combine them with gmapsupp.img files?
As i use the gmap tool and check an older map of MalSing 4.10 , i saw that there were poi in the map which contains blks, post code, etc

Advise would be appreciated.

Thanks
