I was fed up with the battery of the K2, so I decided to buy the Edge 1040 while it was on sale. I'm mostly happy with the switch, but I have a few questions.
1) When I used the K2 with just GPS, I noticed my speed changed a lot when I went through areas with many trees. This was expected and was resolved by using a speed sensor. Now that I have the Edge 1040, I see a similar issue, even though it has multi-band GPS, which I thought would work better. What's more, even with a speed sensor on my front wheel hub, my speed still jumps up and down in tree-covered areas. Does anyone know what could be going on? I didn't think the speed would be affected by trees at all when using a speed sensor.
2) I really like the "back to start" option on the Edge 1040 (the K2 had it too). It lets you return along your route or take the "most direct" path. However, I'm not quite clear on what "direct" means since it could refer to the shortest or fastest way. From what I've seen, it's often neither and sometimes adds extra detours on the way back. Is there a way to set the 1040 to choose either the shortest or fastest route?
Thanks!
