I have spent HOURS researching this, reading every forum I can find (Garmin, Slowtwitch, FB pages, Twitter, etc) and here is where I've finally landed.
- It's a communication problem with the 910 picking up the signal from the power meter. We're supposed to keep it within 42" however a distance greater than 24" is causing the signal to drop and "zeros" to register in our readings. - This is not restricted to one form of Power Meter- Those of us with Quarq, Vector, PowerTap, stages.. we're all having the same problems. This is a GARMIN communication issue with the ANT reader specific to the 910XT (some reports of the 310 also having this issue). - Suggestions of "changing wrists from right to left or left to right" have helped some, but the problem seems to reappear. The only "confirmed" solution is to keep the watch within 24" of the power meter. - Some have written that the 910 quick-release kit has helped them maintain a signal, however those of us using TT bikes (which I would assume is most of us that use a multisport watch) don't have the room on our bars due to aero drink bottles. - Unfortunately GARMIN HAS ABANDONED US ON THIS ISSUE. MANY MANY MANY posts, all with people asking for help. all unanswered. DC Rainmaker recently posted that the team within Garmin that was assigned to work on 910XT issues has been "temporarily reassigned" to work on Vector projects. We are on our own with this. - Known solutions posted by others: Buy a non Garmin based multisport watch (Timex or Polar), or purchase a Garmin Edge for accurate power numbers.
Personally I could not be more disappointed in Garmin and their lack of support for their "flagship" product, we continue to ask for help and we are continually ignored. This watch was marketed as a complete solution for the multisport athlete and we are left with inaccurate distances on the swim GPS, power and cadence numbers that drop too frequently to provide accurate data on the bike, and Heart-rate spikes and crashes on the run that also provide untrustable data.
I'm not sure if this is the problem. My Powertap connects perfectly with my 910 and s further away than the Stages.
From what I've read its an issue with the HRM and Stages. I haven't been able to sort out, and like you I'm very frustrated as it means I have to use both my 510 (which connects perfectly) and 910 when riding my TT bike.
A shame as I like the Stages and love the 910 so far. Can't really afford a 920 at this stage either
