I have a Montana and use basecamp already. Bought a Etrex 35T also which comes with the simpler mapping pre loaded.
I used express to update the 35t and got the option to install the mapping to the PC. But the transfer button is faded out so I cannot do this.
Unlike the montana which when plugged into the PC, I don't get a map to select on the basecamp drop down.
Also get a message about waypoints not been available when plugging in the 35T to basecamp.
So basically I cannot view the preloaded mapping on the 35T or do any routing etc.
Please advise what the issue is? Thanks
