I ran into the same problem with the Icons downloaded from this site. The 3790 seems to be very picky with the BMP format.
Finally got them to work by saving as 8 bit indexed color in Photoshop. I still have not found a way to show transparency...pure magenta does not work for me.
If you loaded the pois and the icons using poiloader then just zoom in on the map. The icons will appear when you get to a scale of 300 feet or so...
Usually this is a double extension problem (ie .bmp.bmp)
Please follow the instruction at
and let us know if this was the problem.
Also, be aware that the 37xx series has a much higher screen resolution, so you need to use larger BMP files in order for them to be seen on the screen. Otherwise, they will be too small.
does it still have the 24 x 24 pixel maximum?
I recall we had a discussion of this a while back, and I made some different sized .bmps for someone to try. They didn't seem to have any luck.
Here are the images again if someone wants to re-try them: http://members.shaw.ca/anon_y_mous/images/
From 30 to 70 px's in size.
if the vechile icon is big (size???) why cant the poi icons be around the same size ,,,,,,has anyone done or tryed this?????
