This is the best map I have found thank you for posting it,

I have a Garmin etrex legend Cx and the map is wonderful,

I created a Directory on my micro SD card called Garmin renamed the file accordingly to gmapsupp.img
Uploaded the img file to the directory and booted the device it recognizes image and works.

It appears to have many points of interest on the map hotels, eatery’s, shops, emergency medical, money exchange, etc etc
some street names are not on the map and as to be expected in Jamaica

hence why they created their JAMNAV system which is based off of points of interest.

Thank you to the author thank you to the creator
This is a wonderful map.
