I have just purchased a 3760t and installed BaseCamp on my MacPro. I have Topo USA 24K Southwest installed in BaseCamp. When I sent to the GPS all that transfers are the waypoints and NOT the routes. I have tried the transfer button and also tried to highlight all the routes and individual routes and drag them to the unit. Nothing seems to work. The routes show up when I look at the 3760 in BaseCamp but not when I look on the unit itself. When I eject the unit I get the following box:
"Some devices were found; however, none have the necessary capabilities.
Please make sure your device is connected to the computer and turned on, then try again.
You may also need to set the interface option on your GPS to 'Garmin' or 'Host'"
Anyone have any thoughts on this please?
Thanks
Steve
