Hello Ron,
- ability to select if I want the distance from speed sensor or GPS. In twisty tree-covered single track it might be that the speed-sensor yields a more accurate distance than GPS, so it would be nice to be able to downgrade to old (non-gps) technology
You already can, if it can't find the speed sensor it takes the GPS automatically. Or go to [MAIN MENU] > [CONFIGURATION] > [ACCESSORIES]
> [SENSORS] > [SPEED] > NO. this thus the job for you.
an odometer reading .. in addition to existing distance (which gets reset upon starting a new activity). This is analogous to an odometer vs trip-distance in a car. Perhaps this is there and I just haven't found it yet. I'm still learning about all the settings.
I like to have all the totals, but it is maybe not so good to have it on the device. A normal bicycle computer battery can last too more than a year, the device in use 18 hours, so if it runs flat you ODO will be lost. Better to have it in TGPro I think. It could be done in the Device but than we need a flash memory type of storage in it.
With regards,
Albert
