60CSx doesnt have built-in memory, it can accept just one map per sd with a map limit of 2 gb( should be 4gb , but with more there are problems) no custom maps.
It has 3axis compass. Quicker fix and maps rendering than in 60CSx.
The ‘Trip computer’ page has a dashboard view, that can include for example an elevation graph.
The elevation plot of each (archived) track can now be viewed on the device itself.
Cant reset odometer (distance meter) to zero using the tripmeter’ ‘reset’-menu.
Paperless and chirp support
Still some bugs, but support is working
60CSx I think is perfect now, stable and reliable ,no bugs,but perhaps old, body plastic shell is better than in 62s, usb is slower.
