I am having Trouble sending maps from Mapsource onto my Garmin 60Csx.
I get the message that the Your GPS does not support Map transfer.
The maps are maps that I have loaded from this site . I had already loaded the maps onto My Garmin and had used them for a month with no problem. Some how I erased them and I Am now trying to reloaded the maps I was using before ,California and Aizonia topo's plus I thought I would add USA 2.0. I am now getting the error message regardless of what maps I try and load.
I found my own problem
The memory chip was loose.
Took it out and reinserted it and the unit worked fine.
Yea, I've had that issue too.
Glad you got it fixed
