I have emailed this enquiry to Garmin as well. As many 60CS users would know by now, when you enter the system screen on startup, a number of readings are given. One of these is the ambient temperature. My limited tests so far indicate that the temperature is relatively accurate.
Does anyone know if Garmin are planning a firmware update that will enable owners to access this information whilst the 60CS is in general use? As it is not practical to be continually turning the unit on and off just to get the temperature.
Perhaps everyone who owns a 60CS should start pestering Garmin to see if they would consider implementing this feature.
They may come back a say it is impossible for whatever reason. But why wouldn't they want to make one of the best units on the market more saleable. It would also be another marketing point over the Magellan unit that measures both temperature and pressure.
