I wasn't sure where to post this, but I'm using an Etrex 30x unit for ultra bikepacking races, and I was wondering if there was any way to update the device to record a power meter, similar to the Edge units. I currently have an Edge 510 with this capability, but would rather use the etrex as I get much better battery life when navigating. Any tips? I'm not super hopeful, as it is a hiking unit, but an update to the software would be awesome.
