Ok for the garmin they rip you off when they sell you a unit and on the box it shows topographic maps and when you get home you realize that you got jerked and are pissed cause they charge you 116 dollars dor each section of topo map.. Well i found a good site that will give you all the FLORIDA TOPO maps for FREEE!!!! with more detail then the garmin ones.. and they also have more states.. i just downloaded it and im so happy i didnt spend the 116 dollars garmin wanted!!!.. All you need is the software that came with your gps unit and the usb wire and BAM.. upload and its game on!!..

I have an older Garmin. Need to see if it is compatible
I dont have any cables for mine. Need to look at it later and see if yours fit
